+JSP Standard Tag Library (JSTL)
+Release: Early Access 2 (EA2)
+
+Thanks for downloading the JSTL EA2 release. We hope you find the tags,
+documents, and examples here of interest. We're curious to hear your
+feedback on this release, which represents work in progress toward a
+standard JSP Tag Library. Please contact us at
+
+ mailto:jsr052-comments@sun.com
+
+with any comments you might have.
+
+Included in this distibution:
+
+ DOCUMENTATION ('doc/web' directory)
+
+ GettingStarted.html: A quick roadmap to help you get started
+ with this release.
+
+ Overview.html: An overview of JSTL's design philosophy and
+ current syntax.
+
+ Functional descriptions: Technical guides representing the
+ design considerations and functionality of JSTL's tag set.
+ Note that these are not formal specifications, just technical
+ overviews of functionality and intent.
+
+ EXAMPLES ('examples' directory)
+
+ The standard-examples application included with this distribution
+ demonstrates the current capabilities of JSTL, exploring idioms
+ and usage patterns when appropriate.
+
+ REFERENCE IMPLEMENTATION ('src' and 'conf' directories)
+
+ Every effort has been made to provide a functional, robust, and
+ speedy reference implementation (RI) for the current functionality
+ JSTL offers. For developers, the code is commented thoroughly
+ to help provide an understanding of design considerations and
+ salient implementation details.
+
+ Classes in the javax.servlet.jsp.jstl represent the current
+ draft of the JSTL API classes. Classes under org.apache.*
+ represent the reference implementation, expected to be released
+ through Jakarta Taglibs. The package structure for the RI is
+ organized as follows:
+
+ org.apache.taglibs.standard
+ .tag tag handlers and routines related to them
+ .common handlers and support routines common for RT/EL attributes
+ .core core library (common)
+ .fmt internationalization-capable formatting tags (common)
+ .xml XML manipulation library (common)
+ .el handlers specific to expression language (EL) evaluation
+ .core core library (EL)
+ .fmt internationalization-capable formatting tags (EL)
+ .xml XML manipulation library (EL)
+ .rt handlers specific to rtexprvalue (rt) evaluation
+ .core core library (rt)
+ .fmt internationalization-capable formatting tags (rt)
+ .xml XML manipulation library (rt)
+ .tei TagExtraInfo classes (common to both libraries)
+ .tlv TagLibraryValidator classes (and associated helpers)
+ .lang expression-language support and implementation
+ .dummy dummy ExpressionEvaluator
+ .support ExpressionEvaluator, ExpressionEvaluatorManager
+ .spel SPEL
+ .jpath JPath
+ .jxpath JXPath
+ .javascript ECMAScript (JavaScript/Rhino)
+
+Enjoy!

+<h3>
+1. Introduction</h3>
+The set of JSTL conditional tags are designed to support the two most
+common usage patterns associated with conditional processing: <i>simple</i>
+conditional execution and <i>mutually exclusive</i> conditional execution.
+The JSTL conditional tags are similar to the XSLT instructions for conditional
+processing (<tt><xsl:if></tt> and <tt><xsl:choose></tt>).
+<p>A simple conditional execution tag evaluates its body content only if
+the test condition associated with it is true. In the following example,
+a special greeting is displayed only if this is a customer's first visit
+to the site.
+<p><tt> <c:if test="$user.visitCount == 1"></tt> <br>
+ <tt> This is your first visit. Welcome to the
+site!</tt>
+<br>
+ <tt> </c:if></tt>
+<p>With mutually exclusive conditional execution, only one among a number
+of possible alternative tags gets its body content evaluated. In the example
+below, the information displayed for a specific product depends on the
+verbosity level selected.
+<p><tt> <choose></tt> <br>
+ <tt> <when test="$verbosityLevel == 'short'></tt> <br>
+ <tt> <c:expr value="$product.shortDescription"/></tt>
+ <br>
+ <tt> </when></tt> <br>
+ <tt> <when test="$verbosityLevel == 'medium'></tt> <br>
+ <tt> <c:expr value="$product.mediumDescription"/></tt>
+ <br>
+ <tt> </when></tt><br>
+ <tt> <otherwise></tt> <br>
+ <tt> <c:expr value="$product.longDescription"/></tt>
+ <br>
+ <tt> </otherwise></tt> <br>
+ <tt> </choose></tt>
+<h3>
+2. <tt><if></tt></h3>
+The <tt><if></tt> tag evaluates its body only if the test condition
+returns true.
+<br>
+<table BORDER CELLSPACING=2 CELLPADDING=5 WIDTH="709" >
+ <tr BGCOLOR="#FFFACD">
+ <th ALIGN=LEFT COLSPAN="4">Attributes</th>
+ </tr>
+ <tr>
+ <td><tt>test</tt></td>
+ <td>required</td>
+ <td>expr</td>
+ <td>The test condition to be evaluated. The value returned by the attribute
+ must either be a <tt>boolean</tt> primitive or a <tt>Boolean</tt> object
+ (EL library). Must be a Boolean object in the RT library.</td>
+ </tr>
+ <tr>
+ <td><tt>var</tt></td>
+ <td>optional</td>
+ <td>string</td>
+ <td>Name of the page scope attribute used to store the current result of the
+ test condition. Visibility is "at_end".</td>
+ </tr>
+</table>
+
+<h3>
+3. <tt><choose></tt></h3>
+The <tt><choose></tt> tag performs conditional block execution embedded
+by the <tt><when></tt> sub tags. It renders the body of the first <tt><when></tt>
+tag whose test condition evaluates to true. If none of the test conditions
+of nested <tt><when></tt> tags evaluate to true, then the body of an
+<tt><otherwise></tt>
+tag is evaluated, if present.
+<p>The <tt><choose></tt> tag has no attributes.
+<h3>
+4. <tt><when></tt></h3>
+The <tt><when></tt> tag is used within a <tt><choose></tt> tag. The
+<tt><choose></tt>
+tag renders the body of the first <tt><when></tt> tag whose test condition
+evaluates to true. The immediate parent of a <tt><when></tt> tag must
+be a <tt><choose></tt> tag, otherwise an exception will be thrown.
+<br>
+<table BORDER CELLSPACING=2 CELLPADDING=5 WIDTH="709" >
+<tr BGCOLOR="#FFFACD">
+<th ALIGN=LEFT COLSPAN="4">Attributes</th>

+
+<tr>
+<td><tt>test</tt></td>

+
+ <td>The test condition to be evaluated. The value returned by the attribute
+ must either be a <tt>boolean</tt> primitive or a <tt>Boolean</tt> object
+ (EL library). Must be a Boolean object in the RT library. </td>
+</tr>
+</table>
+
+<h3>
+5. <tt><otherwise></tt></h3>
+The <tt><otherwise></tt> tag is used as the last subtag within a <tt><choose></tt>
+tag. The <tt><choose></tt> tag renders the body of the <tt><otherwise></tt>
+tag if none of the preceding <tt><when></tt> tags test conditions evaluated
+to true. The immediate parent of an <tt><otherwise></tt> tag must be
+a <tt><choose></tt> tag otherwise an exception will be thrown.
+<p>This tag has no attributes.
+<h3> 6. Custom logic tags</h3>
+It is important to note that <tt><if></tt> and <tt><when></tt> tags
+have different semantics. These semantic differences are enforced by the
+fact that only <tt><when></tt> tags can be used within the context of
+a mutually exclusive conditional execution (<tt><choose></tt> tag).
+<p>This clean separation of behavior also impacts the way custom logic
+tags (i.e. tags who render their bodies depending on the result of a test
+condition) should be developed. Ideally, the result associated with the
+evaluation of custom logic tag should be usable both in the context of
+a simple conditional execution, as well as in a mutually exclusive conditional
+execution.
+<p>The proper way to support this is by simply having a custom logic tag
+export a boolean scripting variable. This boolean scripting variable can
+then be used as the test condition of a <tt><when></tt> subtag. For
+example:
+<p><tt> <paramExists name="hotel" var="needsHotel"/></tt> <br>
+ <tt> <choose></tt>
+<br>
+ <tt> <when test="$needsHotel"></tt> <br>
+ <tt> ...</tt>
+<br><tt> </when></tt>
+<br><tt> <otherwise></tt>
+<br><tt> ...</tt>
+<br><tt> </otherwise></tt>
+<br><tt> </choose></tt>

+<h2> Expression Language Support — Functional Description</h2>
+<hr width="100%" noshade>
+<h3>
+1. Introduction</h3>
+Support for an Expression Language (EL) is a clear requirement for JSTL1.0. We
+need to address this requirement even though it is utimately the responsibility
+of the JSR152 expert group to specify how an EL can be seamlessly integrated in
+JSP, as well as which expression language(s) is/are to be supported by JSP containers.
+<p>In our quest for an interim solution, JSTL is constrained by the fact
+that this solution must work in the context of JSP1.2, without requiring
+any change to the spec, and that it should integrate seamlessly with JSP.next
+(where an EL would be supported natively). It is also important to consider
+the fact that the specification of an expression language is a rather controversial
+issue that could trigger long debates among the expert group, preventing
+us from getting anything out in any timely fashion.
+<p>Our strategy therefore consists in allowing the easy integration, selection,
+and use of a variety of expression languages via an Expression Language
+Integration API, a set of tags, as well as conventions used throughout
+JSTL. We won't rule on any specific EL immediately. Rather we will allow
+various implementations of Expression Languages to all play in our sandbox.
+The hope is that through experimentation, it will be much easier to evaluate
+the merits of each approach, paving the way for the selection of a single
+or limited number of Expression Language(s) for the final draft of JSTL.
+<h3>
+2. Integration of an Expression Language in JSTL1.0</h3>
+An important requirement for support of an Expression Language within JSTL
+was that a single attribute should support a value specified in any of
+the following 3 forms:
+<p><tt> a. String literal
+att="15"</tt>
+<br><tt> b. rtexprvalue
+att="<%= foo.getBar() %>"</tt>
+<br><tt> c. elexprvalue
+att="$foo.bar"</tt>
+<p>This requirement made a lot of sense for the following reasons
+<ul>
+<li>
+logically consistent</li>
+
+<li>
+easy to learn</li>
+
+<li>
+lets our tags transition nicely into the future when JSP.next provides
+native support for an Expression Language</li>
+</ul>
+However, there are many issues in trying to support this given that it
+must work in the context of JSP1.2, without requiring any changes to the
+spec. The most important issue we identified is the danger that an rtexprvalue
+could return a String beginning with '$' (or any other metacharacter used
+by an EL to identify an elexprvalue). This wouldn't be a common 'accidental'
+case, but the fear is that it could become something of a security issue.
+If an rtexprvalue's result is based on user input -- e.g.,
+<p><tt> <%= request.getParameter("username")
+%></tt>
+<p>-- and the user 'maliciously' enters text beginning with '$' in order
+to establish a context for unchecked evaluation of an expression, an application
+might be coerced into acting in unintentional and unpredicted ways.
+To be safe, every rtexprvalue that picks up data from user input would
+need to be wrapped in a routine that escapes a leading '$' if present.
+<p>Because of this security concern, it was decided to use a different
+mechanism to integrate an EL. It consists in using <i>twin</i> tag libraries,
+as described in the next section.
+<h3>
+2. Twin Tag Libraries to support the Expression Language</h3>
+Among the mechanisms that are now available in JSP1.2 is the ability to deliver
+more than one taglib in the same JAR file. JSTL therefore has two flavors of libraries:
+<b>RT</b> (<b>rt</b>exprvalues) and <b>EL</b> (<b>el</b>exprvalues). They only
+differ in the way they support expressions for attribute values.
+<p>In an RT tag library, attributes that support expressions support them as 'rtexprvalues';
+ i.e. as expressions specified in the page's scripting language (and evaluated
+ at runtime). This is exactly how things currently work in tag libraries.
+<p>In an EL tag library, attributes that support expressions support them as 'elexprvalues';
+ i.e. as expressions specified in the JSTL Expression Language (and evaluated
+ at runtime as well). 'rtexprvalues' are not allowed when using an EL tag library.
+ An 'elexprvalue' is a String literal in the syntax of the EL. It is the responsibility
+ of the EL to define the metacharacter(s) used to discriminate expressions from
+ String literals (e.g. use $ at the beginning of an expression).
+<p>JSTL therefore provides two sets of URIs, one for tags that accept rtexprvalues,
+ and one for tags that accept elexprvalues. Twin libraries therefore support
+ the same tags with the same syntax, except that one takes rtexprvalues, the
+ other takes elexprvalues.
+<h4>
+Usage</h4>
+<p>These twin tag libraries can be accessed in the following way in a JSP page
+ (using the "core" taglib as an example):<br>
+ <br>
+ <tt> <%@ taglib uri="http://java.sun.com/jstl/ea/core"
+ prefix="c" %><br>
+ </tt><tt><%@ taglib uri="http://java.sun.com/jstl/ea/core-rt"
+ prefix="c-rt" %></tt> </p>
+<p>In our examples, we append the value '-rt' to differentiate the 'rtexprvalue"
+ library from its 'elexprvalue' twin. It is possible to use the two libraries
+ within the same page, although not recommended for clarity and consistency.
+</p>
+<p>Within the same tag, all attribute values specified as expressions will
+have to be specified either as 'rtexprvalue' or 'elexprvalue' (cannot mix
+within the same tag), depending on which tag library the tag belongs to.
+<h3>
+3. Expression Language Selection</h3>
+It is possible to define a web-application's default expression language
+via the context parameter <tt>javax.servlet.jsp.jstl.temp.ExpressionEvaluatorClass</tt>.
+The class specified must implement interface <tt>ExpressionEvaluator </tt>(see
+below).
+<p>It is also possible to override the default expression language setting
+with the <tt><expressionLanguage></tt> action. For example:
+<p><tt> <jx:expressionLanguage evaluator="<i>evaluator-class</i>"></tt>
+<br><tt> <jx:forEach items="{products/@key}"></tt>
+<br><tt>
+...</tt>
+<br><tt> </jx:forEach></tt>
+<br><tt> </jx:expressionLanguage></tt>
+<p>The scope of the expression language specified by the action <tt><expressionLanguage></tt>
+is limited to its body. <tt><expressionLanguage></tt> actions can be
+nested, where nested occurrences shadow their ancestors .
+<p>It is illegal to use an expression in a context where no expression
+evaluator is specified (i.e., no <tt>web.xml</tt> declaration and no enclosing
+<tt><expressionLanguage></tt>).
+<p>The above rules make it possible to validate the syntax of an
+<tt>elexprvalue</tt>
+at translation time.
+<p>If JSTL rules on a single EL, then both the context parameter and the
+tag will become illegal.
+<h3>
+6. Expression Language API</h3>
+User code is expected to only interact with <tt>ExpressionEvaluatorManager</tt>
+which is reponsible to delegate the requested operation to the currently
+<i>active
+</i><tt>ExpressionEvaluator</tt>.
+[Even if JSTL eventually selects a single EL, this will still be the way
+to access the EL]
+<p><tt> public class ExpressionEvaluatorManager {</tt>
+<br><tt> /**</tt>
+<br><tt> * Invokes the
+evaluate() method on the</tt>
+<br><tt> * "active" ExpressionEvaluator.</tt>
+<br><tt> */</tt>
+<br><tt> public static Object
+evaluate(String attributeName,</tt>
+<br><tt>
+String expression,</tt>
+<br><tt>
+Class expectedType,</tt>
+<br><tt>
+Tag tag,</tt>
+<br><tt>
+PageContext pageContext)</tt>
+<br><tt> throws
+ExpressionException, JspException;</tt>
+<br><tt> }</tt>
+<p>As a result of evaluating an expression, two types of Exceptions can
+be thrown by the ExpressionEvaluator.
+<ul>
+ <li> <tt>JspException</tt></li>
+ <p>Fatal condition that should never be caught by the user code. <br>
+
+ <li> <tt>ExpressionException</tt></li>
+ <br>
+ <p>An error related to the evaluation of a particular exception, which is not
+ expected to cause further problems when evaluating any other expressions.
+ Tags may catch this if they wish to detect failure of an expression to complete
+ evaluation satisfactorily.
+</ul>
+The distinction between these two types of exceptions is useful for actions
+such as <tt><expr></tt> that prefers displaying a default value rather
+than having an error page displayed should an object in the expression
+be inaccessible (e.g. if <tt>address</tt> yielded a null pointer in the
+expression <tt>$customer.address.city</tt>). The EL therefore decides what's
+fatal (<tt>JspException</tt>) and what isn't (<tt>ExpressionException</tt>).
+<p><tt> public class ExpressionException extends JspException;</tt>
+<p>The integration of custom Expression Languages will be possible
+during the Early Access phase of JSTL to help us experiment with various
+ELs. An Expression Language implementation simply needs to implement interface
+<tt>ExpressionEvaluator</tt>.
+Check the details of the JSTL implementation to see if there are any constraints
+on the implementation of an ExpressionEvaluator.
+<br>[For example, one could impose that the implementation of <tt>ExpressionEvaluator</tt>
+be thread-safe, and that there is no guarantee that a single instance
+will be used for all evaluations (if an implementation of an <tt>ExpressionEvaluator</tt>
+wants to store state (such as an expression cache), a static member variable
+with proper synchronization should then be used).]
+<p><tt> public interface ExpressionEvaluator {</tt>
+<br><tt> /**</tt>
+<br><tt> * Translation
+time validation of an expression.</tt>
+<br><tt> * This method
+will return a null String if the expression</tt>
+<br><tt> * is valid; otherwise
+an error message.</tt>
+<br><tt> */</tt>
+<br><tt> public String validate(String
+attributeName,</tt>
+<br><tt>
+String expression);</tt>
+<p><tt> /**</tt>
+<br><tt> * Evaluates the
+expression at request time.</tt>
+<br><tt> */</tt>
+<br><tt> public Object evaluate(String
+attributeName,</tt>
+<br><tt>
+String expression,</tt>
+<br><tt>
+Class expectedType,</tt>
+<br><tt>
+Tag tag,</tt>
+<br><tt>
+PageContext pageContext)</tt>
+<br><tt> throws
+ExpressionException, JspException;</tt>
+<br><tt> }</tt>
+<h3>
+7. Custom Tags using the JSTL Expression Language(s)</h3>
+Custom tag developers can support expression languages in their tags using
+the same conventions established in this document.
+<p>Assuming a custom action named <tt>foo</tt>; one could have the following
+implementation classes:
+<p><tt> FooTag</tt>
+<br><tt>
+/ \</tt>
+<br><tt> /
+\</tt>
+<br><tt> FooTagRT FooTagEL</tt>
+<p>The only code in FooTagRT and FooTagEL are the setter and getter methods
+for the attributes that support expressions (they cannot be inherited because
+the properties do not have the same type; String for EL and the "native"
+type for RT).
+<p>FooTagEL also needs to override doStartTag() to evaluate the elexprvalue
+first, and then call back into the base class. For example:
+<p><tt> public void setFoo(String fooEL) throws JspException {</tt>
+<br><tt> this.fooEL = fooEL;</tt>
+<br><tt> }</tt>
+<p><tt> public int doStartTag() throws JspException {</tt>
+<br><tt> foo = ExpressionEvaluatorManager.evaluate</tt>
+<br><tt>
+("foo", fooEL, FooType.class, this, pageContext);</tt>
+<br><tt> }</tt>
+<br><tt> return super.doStartTag();</tt>
+<br><tt> }</tt>
+<p>It is important to note that the evaluation of the expression must be
+performed within the <tt>doStartTag()</tt> method. The lifecycle of a tag
+is such that the setter method of values that no not change (string literals)
+may not necessarily be called if the tag is reused by the container. Since
+an elexprvalue is specified as a string literal, this could cause an elexprvalue
+to not to be "re-evaluated" if the evaluation were to be performed in the
+setter method.
+<p>Two TLDs must be written. The only differences are:
+<ul>
+<li>
+tool support info elements (short-name, description, etc...)</li>
+
+<li>
+<uri></li>
+
+<br>(e.g. "http://acme.com/mytaglib-rt", "http://acme.com/mytaglib-el")
+<li>
+<tag-class> for each attribute that supports expression values</li>
+
+<br>(e.g. FooTagRT vs FooTagEL)
+<li>
+<rtexprvalue> true for the RT tag library, false for EL tag library</li>
+</ul>
+When JSP.next comes, a unified tag library can be created. All there is
+to do is merge the base classes with the RT classes, and remove the 'EL'
+classes and the EL TLD.
+<h3>
+8. Validation of elexprvalues at translation time</h3>
+@@@ FIXME During the Early Access phase where multiple ELs are made available
+for experimentation, translation time validation of elexprvalues must be performed
+by a TagLibraryValidator so the proper ExpressionEvaluator can be invoked for
+the validation (a TEI would not be able to establish the execution context). One
+such TagLibraryValidator, <tt>ExpressionEvaluatorTLV</tt>, is made available
+to support translation time validation of elexprvalues of JSTL tags, as well
+as for any other custom tag library.
+<p>It supports an initialization parameter (<tt>custom-taglibs)</tt> to
+specify the list of custom tag libraries that should be validated for elexprvalues
+(* to specify all).
+<p>For example:
+<p><tt> <taglib></tt>
+<br><tt> ...</tt>
+<br><tt> <validator></tt>
+<br><tt> <validator-class>javax.servlet.jsp.jstl.core.ExpressionEvaluatorTLV</validator-class></tt>
+<br><tt> <init-param></tt>
+<br><tt> <param-name>custom-taglibs</param-name></tt>
+<br><tt> <param-value>*</param-value></tt>
+<br><tt> </init-param></tt>
+<br><tt> </validator></tt>
+<br><tt> ...</tt>
+<br><tt> </taglib></tt>
+<p>If the JSTL ends up specifying a single EL, then translation-time validation
+could be performed within the TagExtraInfoClass by simply calling <tt>ExpressionEvaluatorManager.validate()
+</tt>on
+each elexprvalue.
+<h3>
+9. Relationship with future JSP specs</h3>
+The expression language integration model for JSTL will work fine with
+JSP 1.2 containers and above. Nothing in that model gets in the way of
+the JSP specification should it decide to include native support for expression
+language(s).
+<p>When a JSP spec comes with native support for an EL (JSP.next), the
+assumption is that EL expressions would be supported natively only for
+attributes where rtexprvalue=true.
+<p>The twin libraries would behave as follows in a JSP.next environment:
+<ul>
+<li>
+<b>JSTL-1.0-RT</b></li>
+
+<br>Will keep working as before, with the addition that it will also be
+possible to specify elexprvalues.
+<li>
+<b>JSTL-1.0-EL</b></li>
+
+<br>Tags will keep working exactly as before; no change. The elexprvalues
+will still be evaluated by the tag library, and not the container since
+rtexprvalue=false for all attributes in that tag library.</ul>
+The only drawback to the semantics of 'EL is only interpreted in a rtexprvalue
+attribute' is that somebody can type a="$expr" and get a literal when they
+really meant "evaluate expr".
+<p>Is it important or not? One may argue that most attributes support rtexprvalues,
+except for the few cases where the value needs to be known at translation
+time (in which case elexprvalues cannot be used). For example:
+<ul>
+<li>
+scripting variable names</li>
+
+<li>
+value is the *type* of a scripting variable exported by the tag</li>
+
+<li>
+value needs to be known by a validator (e.g., for the <jsptl:expressionLanguage>
+tag)</li>
+</ul>
+This is a JSP.next issue. If this is seen as an important issue, it could
+be made a translation-time error to use unescaped $ syntax in a non-rtexpr
+attribute. But this would have the disadvantage of breaking JSPs that use
+the EL version of the twin tag libraries.
+<p>At the same time as JSP.next comes out, the goal would be to have a
+new version of the tag library that removes the distinction between RT
+and EL. For example: "http://java.sun.com/jsptl-1.0" (no suffix). The TLD
+would state a dependency on JSP.next.

+of the evaluation to the current JspWriter object. It is the equivalent
+of <tt><%= %></tt> with the difference that it is meant for the Expression
+Language world (as opposed to the scripting language world).
+<p>The expression to be evaluated is specified via the attribute <tt>value</tt>
+and must be in the syntax of the current Expression Language. The result
+of the evaluation is coerced to a String and is subsequently emitted into
+the current JspWriter object.
+<p>For example:
+<p><tt> Hello <c:expr value="$request:name"/></tt>
+<p>is equivalent to
+<p><tt> Hello <%=pageContext.getAttribute("name", PageContext.SCOPE_REQUEST)%></tt>
+<p>assuming the expression language interprets the elexprvalue <tt>$request:name</tt>
+as meaning the value of the name attribute in the request scope.
+<p>As a convenience, this action also supports the notion of <i>default value</i>
+ for cases where the value of an object in the elexprvalue is not accessible.
+ The default condition is triggered when the Expression Language throws an ExpressionException
+ while evaluating the expression (to report failure to complete evaluation satisfactorily)
+ or if the evaluation of the expression completes, but the result is null. This
+ condition usually happens when one of the objects in the expression is null.
+ For example, in the example below, this exception would be thrown if the address
+ property of the customer object were null. Check the details of the expression
+ language to clearly understand under which circumstances the ExpressionException
+ is thrown.
+<p>The default value can be specified either via attribute <tt>default:</tt>
+<p><tt> <c:expr value="$customer.address.city" default="unknown"/></tt>
+<p>or within the body of the tag:
+<p><tt> <c:expr value="$customer.address.city"></tt>
+<br><tt> <acme:defaultCity/></tt>
+<br><tt> </c:expr></tt>
+<p>The two ways to specify a default value cannot be used simultaneously.
+<p>The <tt><expr></tt> action is only available in the EL version of
+ the library.
+<h3>
+2. <tt><set></tt></h3>
+The <tt><set></tt> action sets the value of an attribute in any of the
+JSP scopes (page, request, session, application). If the attribute does
+not already exist, it is created.
+<p>The JSP scoped attribute can be set either from attribute value:
+<p><tt> <c:set var="foo" scope="session" value="..."/></tt>
+<p>or from the body of the tag:
+<p><tt> <c:set var="foo"></tt> <br>
+ <tt> ...</tt>
+<br><tt> </c:set></tt>
+<p>Setting the value of a JSP scoped attribute from the tag's body content
+is useful to solve the problem associated with the fact that a tag attribute's
+value cannot be set from a tag. In the past, a tag developer would have
+to offer extra "attributes as tags" so the value of these attributes could
+be set from other tags. For example:
+<p><tt> <acme:atag></tt> <br>
+ <tt> <x:att1><x:foo>mumbojumbo</x:foo></x:att1></tt>
+<br>
+ <tt> </acme:atag></tt>
+<p>With the <tt><set></tt> tag, this can be handled without requiring
+the extra <tt><att1></tt> tag.
+<p><tt> <c:set var="att1"><x:foo>mumbojumbo</x:foo></c:set></tt>
+ <br>
+ <tt> <acme:atag att1="$att1"/></tt>
+<p><font size=+0>Attribute <tt>scope</tt> is used to specify the scope
+of the JSP attribute targetted by the <set> tag. It is an optional attribute
+that defaults to "page". The accepted values are restricted to: page, request,
+session, and application.</font>
+<p><font size=+0>The <set> tag is only available in the EL version of the library</font><font size=+0>.</font>
+<h3> 3. <tt><declare></tt></h3>
+Given that an Expression Language is supported in JSTL, the need for scripting
+should be reduced substantially. However, until a JSP.next comes around
+with native support for the Expression Language, page authors will still
+have to deal with situations where some attributes of non-JSTL tags must
+be specified as rtexprvalues.
+<p>For example, <myTag> below expects to receive an "Order" object using an
+ rtexprvalue. Because <code>var</code> is not exported as a scripting variable
+ in the <forEach> tag, the code below would trigger a translation time error
+ because the scripting variable customer does not exist.
+<p><tt> <c:forEach items="$customers" var="customer"></tt>
+ <br>
+ <tt> <acme:myTag order=<%=customer.getOrder()%>
+/></tt>
+<br><tt> </c:forEach></tt>
+<p>There needs to be a simple way to define a scripting variable to bridge
+the gap between the EL and scripting worlds until JSP.next comes.
+<p>The <tt><declare></tt> tag is used for that purpose. In the example below,
+ a scripting variable "customer" is created as a reference to the JSP scoped
+ attribute of the same name.
+<p><tt> <c:forEach items="$customers" var="customer"></tt>
+ <br>
+ <tt> <c:declare id="customer"
+ type="acme.Customer"/></tt> <br>
+ <tt> <acme:myTag order=<%=customer.getOrder()%>
+/></tt>
+<br><tt> </c:forEach></tt>
+<p>When jsp.next comes, the above code would simply become:
+<p><tt> <c:forEach items="$customers" var="customer"></tt>
+ <br>
+ <tt> <acme:myTag order="$customer.order"
+/></tt>
+<br><tt> </c:forEach></tt>
+<p>without requiring any modification to the <tt><acme:myTag></tt> tag.
+<p>The same requirement for a bridge between the EL and scripting worlds exists
+ whether a page author uses the EL or RT version of JSTL. This tag therefore
+ exists in both the EL and RT versions of thelibrary.
+<ul>
+ <li> <b><tt>id</tt></b> The name of the scripting variable to be exported</li>
+ <li> <b><tt>type</tt></b> The type of the scripting variable. Optional. Defaults
+ to java.lang.Object.</li>
+</ul>
+The visibility of the scripting variable is always AT_END. <br>

+<h1>Getting started with JSTL (EA2)</h1>
+
+<p>This document describes how to get up and running quickly with JSTL's
+second early-access release. It can be useful to page authors and tag
+developers who are interested in JSTL's functionality. Using the
+"jstl-examples" application is also a great way to familiarize yourself
+with JSTL's functionality and use.</p>
+
+<p><b>IMPORTANT:</b> This release of JSTL is an early-access release and
+does not represent a standard of any kind. The API and implementation are
+subject to change in the future. The major purpose of this release is to
+provide early information to the community of JSP developers about the
+direction and scope of JSTL. Community feedback is actively sought; if
+you have any comments, please email us at
+<a href="mailto:jsr052-comments@sun.com">jsr052-comments@sun.com</a>.

+<hr />
+<h2>Introduction</h2>
+
+<a name="#1.1" />
+<h3>What is JSTL? Where does it come from?</h3>
+
+<p>JSTL is the JSP(tm) Standard Tag Library. It is an effort of the Java
+Community Process (JCP) and comes out of the JSR-052 expert group.</p>
+
+<a name="#1.2" />
+<h3>What does JSTL do?</h3>
+
+<p>JSTL encapsulates, as simple tags, core functionality common to many
+JSP applications. For example, instead of suggesting that you iterate
+over lists using a scriptlet or different iteration tags from
+numerous vendors, JSTL defines a standard <forEach> tag that works
+the same everywhere.</p>
+
+<p>This standardization lets you learn a single tag and use it on multiple
+JSP containers. Also, when tags are standard, containers can recognize
+them and optimize their implementations.</p>
+
+<p>The current early-access release of JSTL has support for core iteration
+and control-flow features, text inclusion, internationalizaton-capable
+formatting tags, and XML-manipulation tags. It also supports an
+<i>expression language</i> to simplify page development, and it includes
+an experimental version of several such languages for testing purposes.
+Developers may also be interested in JSTL's current extensibility
+mechanisms; JSTL currently provides a framework for integrating custom
+tags with JSTL tags.</p>
+
+<h3>What does "early access" mean?</h3>
+
+<p>As we noted above, <b>this release of JSTL is not an official release;
+it does not represent a final standard of any kind</b>. Basing production
+systems on the APIs and implementations offered here is not advised. The
+good news is that you still have time to comment on JSTL before it is
+finalized: mail us at <a href="mailto:jsr052-comments@sun.com">
+jsr052-comments@sun.com</a> if you have any comments.</p>
+
+<h3>What has changed since EA1?</h3>
+<p>Please see the <a href="ReleaseNotes.html">Release Notes</a> document
+for information on JSTL RI changes.</p>
+
+<hr />
+<h2><a name="#2" />Getting started quickly</h2>
+
+<p>JSTL EA2 uses features provided only by the JSP 1.2 standard draft, so
+it requires a JSP 1.2 container. We recommend you test JSTL with Tomcat
+4.0.</p>
+
+<p>To install Tomcat, follow the instructions at <a
+href="http://jakarta.apache.org/tomcat">http://jakarta.apache.org/tomcat</a>.
+To install the JSTL libraries for use in a web application, follow the
+instructions at <a
+href="http://jakarta.apache.org/taglibs/binarydist.html">
+http://jakarta.apache.org/taglibs/binarydist.html</a>. You can also use
+the "jstl-examples" application as a guide.</p>
+
+<!--
+<p>If your web application does not already use an XML parser, you will
+need to make one available because current versions of Tomcat do not. See
+the Tomcat 4 release notes (RELEASE-NOTES-4.0-B7.txt in the top level
+directory of your Tomcat distribution) for more information about XML
+parsers in Tomcat 4.</p>
+-->
+
+<h3>Multiple tag libraries</h3>
+
+<p>See the <a href="Overview.html">Overview Document</a> for information
+on JSTL's constituent tag libraries. That document lists JSTL's
+current TLD URIs and recommended taglib prefixes.</p>
+
+<p>Using the JSTL libraries is simple; you simply need to import them into
+your JSP pages using the <b>taglib</b> directive. For instance, to import
+the core JSTL library into your page, you would include the following line
+at the top of your JSP page, as follows:</p>
+
+<pre>
+ <%@ taglib uri="http://java.sun.com/jstl/ea/core" prefix="c" %>
+</pre>
+
+<h3>Expression languages</h3>
+
+<p>Half of JSTL's tag libraries -- the recommended ones -- rely on an
+expression language. To facilitate experimentation and feedback, the
+JSTL RI currently lets you switch between a number of different languages.
+For EA2, the ECMAScript language is the default.</p>
+
+<p>The expression language for a web application is configured by
+setting the servlet context parameter
+<tt>javax.servlet.jsp.jstl.temp.ExpressionEvaluatorClass</tt> to the class
+containing the expression-evaluation logic you wish to use. In
+<tt>jstl.jar</tt>, the SPEL is identified by the class
+<tt>org.apache.taglibs.standard.lang.spel.Evaluator</tt>; JPath is identified
+by the class
+<tt>org.apache.taglibs.standard.lang.jpath.JPathExpressionEvaluator</tt>;
+JXPath's evaluator is
+<tt>org.apache.taglibs.standard.lang.jxpath.JXPathExpressionEvaluator</tt>;
+and the JavaScript/Rhino evaluator is
+<tt>org.apache.taglibs.standard.lang.javascript.javascript.JavascriptExpressionEvaluator</tt>.
+(For an example of how this context parameter is set, see the
+<tt>web.xml</tt> file that comes with the <tt>jstl-examples</tt>
+application.)</p>
+
+<p>In JSTL EA2, you can also mix different expression languages on the
+same page using the <tt><expressionLanguage></tt> tag. This tag's
+<tt>evaluator</tt> attribute points to the class containing the
+expression-evaluation logic you wish to use. See the Functional
+Description of expression-language support for more information.</p>
+
+<p>The attributes in tags for the EL version of the library do not accept
+rtexprvalues. Instead, you specify literal expressions that the tags
+evaluate at runtime. For example:</p>
+
+<pre>
+ <jx:forEach items="<b>$page:myItems</b>" />
+</pre>
+
+<i><b>Important:</b> The expression-language support included with JSTL
+JSTL EA2 should be considered even more experimental than the rest of the
+package. You should not assume that either the "pluggability" mechanism
+or the prepackaged languages themselves will remain in JSTL's final
+version, or even in the next EA releases.</i>
+
+<h3>Topics covered in JSTL EA2</h3>
+
+<p>As we mentioned above, JSTL EA2 includes core tags to support
+iteration, conditionals, and expression-language support. For more
+information on precisely how these tags work, you should read the
+"Functional Description" documents provided as part of this distribution.
+Here, we just offer a quick roadmap of each feature in order to help
+orient you.</p>
+
+<dl>
+<dt><b>Iteration</b></dt>
+
+<dd>The core iteration tag is <forEach>, which iterates over most
+collections and similar objects you'd think to iterate over.
+<forTokens> lets you iterate over tokens in a <tt>String</tt>
+object; it lets you specify the <tt>String</tt> and the delimiters.</dd>
+
+<dt><b>Conditionals</b></dt>
+
+<dd>JSTL EA2 supports a simple conditional <if> tag along with
+a collection of tags -- <choose>, <when>, and <otherwise>
+-- that support mutually exclusive conditionals. These latter three
+tags let you implement a typical <tt>if/else if/else if/else</tt>
+structure.</dd>
+
+<dt>
+<b>Expression languages</b></dt>
+
+<dd>We described the EL support in JSTL EA2 above. In addition to
+<expressionLanguage>, JSTL EA2 provides a few other tags to
+facilitate use of expression language. <expr> prints out the value
+of a particular expression in the current EL, similar to the way that the
+scriptlet expression (<%= ... %=>) syntax prints out the value of a
+expression in the scripting language (typically Java). <set> lets
+you set a scoped attribute (e.g., a value in the request, page, session,
+or application scopes) with the value of an expression.</dd>
+
+<dt>
+<b>Text inclusion</b></dt>
+
+<dd>JSP supports the <tt>jsp:include</tt> tag, but this standard action is
+limited in that it only supports relative URLs. JSTL EA2 introduces the
+<tt>c:import</tt> tag, which lets you retrieve absolute URLs. For
+instance, you can use <tt>c:import</tt> to retrieve information from the
+web using HTTP URLs, or from a file server using an FTP URL. The tag also
+has some advanced support for performance optimizations, avoiding
+unnecessary buffering of data that's retrieved.</dd>
+
+<dt>
+<b>I18N-capable text formatting</b></dt>
+
+<dd>Formatting data is one of the key tasks in many JSP pages. JSTL
+introduces tags to support data formatting and parsing. These tags
+rely on convenient machinery to support internationalized applications.
+</dd>
+
+<dt>
+<b>XML manipulation</b></dt>
+
+<dd>You can't look anywhere these days without seeing XML, and JSTL
+gives you convenient support for manipulating it from your JSP pages.
+Parse documents, use XPath to select content, and perform XSLT transformations
+from within your JSP pages.</dd>
+
+</dl>
+
+<h3>For tag developers...</h3>
+
+<p>Developers of custom tags should also read the "Functional
+Descriptions" provided for each topic addressed by JSTL EA2. JSTL EA2
+provides some abstract classes that assist with rapid development of tags
+and promote integration of custom tags with JSTL's tag set.</p>
+
+<p>For instance, custom tags can use JSTL's expression-language
+mechanism. As another example, extending
+<tt>javax.servlet.jsp.jstl.core.ConditionalTagSupport</tt> lets you write a
+conditional tag by merely implementing a single method that returns a
+<tt>boolean</tt> value correspondent with your tag's desired conditional
+behavior; also, this base class promotes JSTL's recommended model of
+conditional-tag design.</p>
+
+<p>Similarly, <tt>javax.servlet.jsp.jstl.core.IteratorTagSupport</tt> lets
+you easily implement iteration tags. The handlers for the <forEach>
+and <forTokens> tags extend this class and thus implement the
+<tt>javax.servlet.jsp.jstl.core.IteratorTag</tt> interface, which provides
+a well-defined mechanism for iteration tags to communicate with custom
+subtags you can write. See the "jstl-examples" application for one
+example of how you might use such custom subtags.</p>

+<h3> 1. Introduction</h3>
+<p>In the JSP specification, a <jsp:include .../> element provides for the
+ inclusion of static and dynamic resources in the same context as the current
+ page. This is a very convenient feature that is widely used by page authors.
+</p>
+<p>However, <jsp:include> falls short in flexibility and efficiency when
+ page authors need to get access to resources that reside outside of the web
+ application, as well as when the content of the imported resource is used as
+ the source for a companion process/transformation element. More specifically:</p>
+<blockquote>
+ <p><b>Limited to web-app resources</b></p>
+ <p><jsp:include> only supports the inclusion of resources within the same
+ web application. In many situations, page authors have the need to import
+ the content of internet resources specified via an absolute URL. Moreover,
+ as sites grow in size, they may have to be implemented as a set of web applications
+ where importing resources across web-applications is a requirement.</p>
+ <p><b>Unnecessary buffering when the resource included is fed into another element
+ </b> </p>
+ <p>In the example below, the <transform> element uses the content of the
+ included resource as the input of its transformation. The <jsp:include>
+ reads the content of the response, writes it to the body content of the enclosing
+ <transform> element, which then re-reads the exact same content. It
+ would be more efficient if the <transform> element could access the
+ input source directly and avoid the buffering involved in the body content
+ of the <transform> tag.</p>
+ <pre> <acme:transform>
+ <jsp:include page="/exec/employeesList"/><br> <acme:transform/></pre>
+</blockquote>
+<p>The <import> tag has been designed to address the above shortcomings.</p>
+<h3>2. <import></h3>
+<p>There is a wide variety of resources that a page author might be interested
+ in including and/or processing within a JSP page. For instance, the example
+ below shows how the content of the README file at the ftp site of acme.com could
+ be included within the page.</p>
+<blockquote>
+ <p><code><c:import url="ftp://ftp.acme.com/README"/></code></p>
+</blockquote>
+<p>The main motivation behind <import> is to provide a simple, straightforward
+ mechanism to access resources that can be specified via a URL, nothing more.
+ If accessing a resource requires specifying more arguments, then a protocol
+ specific action (e.g. an <http> action) should be used for that purpose.
+ JSTL1.0 does not currently address these protocol specific elements but may
+ do so in future releases.</p>
+<p><import> is therefore the simple, generic way to access URL based resources
+ whose content can then be included and or processed within the JSP page.</p>
+<p><b>Exporting an object: String or Reader</b></p>
+<p>By default, the content of the resource is included inline into the JSP page.
+</p>
+<p>It is also possible to export the content of the resource in two different
+ ways: as a String object (attribute "var"), or as a Reader object
+ (attribute "varReader"). Process/Transform tags can get access to
+ a resource's content through that exported object. Only one of "var"
+ and "varReader" can be specified.</p>
+<p>Simplest way to export the resource content as an object is via the "var"
+ atttibute. The data is <i>cached</i> in a String object and is <i>reusable</i>.
+</p>
+<p>Although more complex in its usage, there may be some performance gains if
+ the resource content is exported as a Reader object (instead of String object).
+ Depending on the implementation and on the type of URL being accessed, it may
+ be possible to access the content directly, without any unnecessary buffering.
+ But please note that there are no performance guarantees; this is an implementation
+ detail.</p>
+<p>The use of the varReader attribute comes with some restrictions. It is the
+ responsibility of the <import> tag to ensure that if a Reader object is
+ exported, it is properly closed by the end of the page.<br>
+ <font size="-1">[If the responsibility was left to the consumer tag, this could
+ lead to resource leaks (e.g. connection left open, memory space for buffers)
+ until garbage collection is activated if a consumer tag would not close the
+ Reader, or simply if the page author would remove the consumer tag while leaving
+ inadvertantly the <import> tag in the page.]</font></p>
+<p>Because of this, the visibility of a varReader object is nested, so that the
+ Reader may be properly closed when reaching the closing </import>. It
+ therefore makes sense to export a Reader object only when the <import>
+ has nested content that consumes the resource. Using a bodyless <import>
+ tag with varReader is flagged as an error at translation time.<br>
+ <font size="-1">[This restriction could eventually be lifted when the JSP spec
+ supports the notion of page events that actions could register to. On a <i>pageExit</i>
+ event, an <import> tag would then simply release its resources if it had
+ not already been done, removing the requirement for nested visibility. An RFE
+ has been submitted to the JSP expert group.]</font></p>
+<p>It is also illegal to use nested <param> tags with varReader.<br>
+ <font size="-1">[Because varReader takes an arbitrary body and exposes a Reader
+ for it, it needs to open a connection when the start tag is encountered. But
+ if it opens the connection there, it won't have had a chance to hear from its
+ <param> subtags (which modify the URL that <import> connects to).]</font></p>
+<p><b>Character Encoding</b></p>
+<p>When the var attribute is used to expose a Reader object, it is possible to
+ specify the character encoding of the content at the input resource. For example:</p>
+<pre> <c:import url="..." varReader="doc" charEncoding="..."/></pre>
+<p>If the character encoding is not specified, the following rules apply:</p>
+<ul>
+ <li>If the response of the <import> request has a "content-type"
+ header field, then the character encoding specified is used (the imported
+ resource tells us about its encoding, we just use it)</li>
+ <li>Use ISO-8859-1 (which is the default value of charset for the contentType
+ of the JSP "page" directive)</li>
+</ul>
+<p>Note that the charEncoding attribute should normally only be required when
+ accessing absolute URL resources where the protocol is not HTTP, and where the
+ encoding is not ISO-8859-1.</p>
+<p>Also, when dealing with relative URLs and the HTTP protocol, if the target
+ resource declares a content encoding but proceeds to write a character invalid
+ in that encoding, the treatment of that character is undefined.</p>
+<h3>3. Relative and Absolute URLs</h3>
+<p>The <code>url</code> attribute is used to specify the URL of the resource to
+ access. It can either be an absolute URL (i.e. one that starts with a protocol
+ followed by a colon), a relative URL used to access a resource within the same
+ context, or a relative URL used to access a resource within a foreign context
+ (context name must be specified).</p>
+<p>The exact semantics of the <import> tag depends on what type of URL is
+ being accessed.</p>
+<p><b>Relative URL - same context</b></p>
+<p> This is processed in the exact same way as the standard include action (<jsp:include>)
+ of the JSP specification. The resource belongs to the same web-app as the including
+ page and it is specified as a relative URL. For example:</p>
+<pre> <c:import url="/copyright.html"/></pre>
+<p>As specified in the JSP spec, a relative URL may either be a <i>context-relative</i>
+ path, or a <i>page-relative</i> path. A context-relative path is a path that
+ starts with a “/”. It is to be interpreted as relative to the application
+ to which the JSP page belongs. A page-relative path is a path that does not
+ start with a “/”. It is to be interpreted as relative to the current
+ JSP page.</p>
+<p>The semantics of importing a resource specified with a relative URL in the
+ same context are the same as an include performed by a RequestDispatcher in
+ the Servlet specification. This means that the whole environment (request, session,
+ application) of the importing page is available to the target resource (including
+ request parameters of the importing page).</p>
+<p><b>Relative URL - foreign context</b><br>
+</p>
+<p> The resource belongs to a foreign context (web application) hosted under the
+ same container as the importing page. The context name for the resource is specified
+ via argument "context". For example:</p>
+<pre> <c:import url="/logo.html" context="/master"/></pre>
+<p>The relative URL must be context-relative (i.e. must start with a "/")
+ since the including page does not belong to the same context. Similarly, the
+ context name must also start with a "/".</p>
+<p>The semantics of importing a resource specified with a relative URL in a foreign
+ context are the same as an include performed by a RequestDispatcher on a foreign
+ context in the Servlet specification. This means that only the "request"
+ environment of the importing page is available to the target resource.</p>
+<p>It is important to note though that importing resources in foreign contexts
+ may not work in all containers. A security conscious environment may not allow
+ access to foreign contexts. As a workaround, a foreign context resource can
+ also be accessed using an absolute URL. For example:</p>
+<pre> <c:import url="http://www.acme.com/master/logo.html"/></pre>
+<p>However, it is much more efficient to use a relative URL because the resource
+ is then accessed using RequestDispatcher of the servlet API. </p>
+<p><b>Absolute URL</b></p>
+<p>Given that JSP1.2 assumes a J2SE platform at a minimum, the <import>
+ tag therefore supports at a minimum the protocols offered in that platform for
+ absolute URLs. More protocols can still be available to a web application, but
+ this will depend on the the class libraries made available to the webapp by
+ the platform the container runs on.</p>
+<p>The example below shows how a request is sent to a remote site to obtain a
+ list of customers, and how that list is then used as input to a notification
+ tag.</p>
+<pre> <c:import url="http://acme.com/exec/customers?country=USA" var="customers"/><br> <acme:notify in="$customers"/></pre>
+<p>When using an absolute URL to import a resource, none of the current execution
+ environment (request, session, application) is made available to the target
+ resource, even if that absolute URL resolves to the same host and context path.
+ Therefore, the request parameters of the importing page are not propagated to
+ the target "absolute URL".</p>
+<h3><b>4. <urlEncode></b></h3>
+<p>URL encoding refers to the process of encoding special characters in a string,
+ according to the encoding rules defined in RFC 1738 (section 2.2. URL Character
+ Encoding Issues). </p>
+<p>For example, a space must be encoded in a URL string as a '+':</p>
+<blockquote>
+ <p><code>http://www.acme.com/app/register?name=Aristide+Bertrand&country=Republique+Dominicaine
+ </code> </p>
+</blockquote>
+<p>The <urlEncode> action will encode the string specified in attribute
+ 'value'. If the value attribute is not specified, encoding is performed on the
+ tag's body content.</p>
+<p>By default, the result of the encoding is written to the page. It is also possible
+ to export the result of the encoding as a JSP scoped attribute (java.lang.String)
+ defined via attribute "var". For example:</p>
+<pre> <urlEncode var="nameEncoded" value="$name"/>
+</pre>
+<p>With respect to the <import> tag, it is important to note that all URLs
+ need to be encoded. However, URL encoding is normally necessary only when dealing
+ with query string parameters.</p>
+<p>For example, assuming the following absolute URL</p>
+<blockquote>
+ <p><code>http://www.acme.com/app/register</code></p>
+</blockquote>
+<p>to which two query string parameters must be passed: "name" and "country",
+ both of which are retrieved from JSP scoped attributes. Since special characters
+ can be part of these scoped attributes, they must be encoded before they can
+ be added to the URL. This could be done as follows:</p>
+<blockquote>
+ <p> <code><urlEncode var="nameEncoded" value="$name"/><br>
+ <urlEncode var="countryEncoded" value="$country"/><br>
+ <c:import url="$'http://www.acme.com/app/register?name='+nameEncoded+'&country='+countryEncoded"/></code></p>
+</blockquote>
+<p>However this is somewhat awkward. A better way is to use nested <param>
+ tags to specify the query string parameters to be added to the URL. As a convenience,
+ the <param> action has been designed such that query string parameters
+ (both "name" and "value") are automatically encoded for
+ the <import> action. The following could therefore be used without having
+ to worry about any encoding:</p>
+<blockquote>
+ <pre><c:import url="http://www.acme.com/app/register">
+ <param name="name" value="$name"/>
+ <param name="country" value="$country"/>
+</c:import></pre>
+</blockquote>
+<h3>5. <param></h3>
+<p>The <param> element can be used with <import> to specify request
+ parameters.</p>
+<p>One might argue that this is redundant given that the URL can be constructed
+ to include query string parameters.</p>
+<p>For example:</p>
+<pre> <c:import url="/exec/doIt><br> <c:param name="action" value="register"/><br> </c:import></pre>
+<p>is the same as:</p>
+<pre> <c:import url="/exec/doIt?action=register"/></pre>
+<p>It is indeed redundant, but is consistent with <jsp:include> supporting
+ nested <jsp:param> sub-elements. Moreover, it has been designed such that
+ the parameter "name" and "value" are automatically <i>url
+ encoded</i> (as described in the previous section). Automatic encoding can be
+ disabled using optional attribute "encode", whose value defaults to
+ "true" otherwise.</p>
+<p>It is important to note that that the query parameter aggregation rules work
+ the same way they do with <jsp:include>; the original parameters are augmented
+ with the new parameters, with new values taking precedence over existing values
+ when applicable.The scope of the new parameters is the import call; the new
+ parameters (and values) will not apply after the import. This is the same behavior
+ as in the ServletRequest include and forward methods (see Section 8.1.1 in the
+ Servlet 2.2 specification).</p>
+<p>For example:</p>
+<pre> <c:import url="http://acme.com/exec/doIt?foo=foovalOne"/><br> <c:param name="foo" value="fooval 2"/><br> <c:param name="bar" value="bar value"/><br> </c:import>
+</pre>
+modifies the absolute URL as follows:
+<pre> http://acme.com/exec/doIt?foo=fooval+2&bar=bar+value&foo=foovalOne</pre>

+<h3>6. Notes</h3>
+<ul>
+ <li>
+ <p><c:import> tags are all independent from one another; they do not
+ create an implicit session among themselves using cookies.
+ </li>
+ <li>There is no way using the <import> tag to authenticate to a URL that
+ requires HTTP basic authentication.</li>
+</ul>
+<h3>7. Design decisions of interest</h3>
+<p>We know you'd eventually ask these questions. Here are the answers...</p>
+<p><b><a name="map"></a>Transparently map absolute URLs to relative ones when
+ possible? No.</b></p>
+<p>If a resource is specified as an absolute URL, it may still refer to a resource
+ located on the same container (same or foreign context). Why not have the <import>
+ tag transparently map absolute URLs to relative ones when possible to improve
+ performance? </p>
+<p>We've decided against it simply because doing things behind the scenes may
+ lead to confusion. Users should understand the difference between absolute and
+ relative URLs, and the impact of using one vs the other in terms of performance
+ as well as execution environment of the imported resource.</p>
+<p>So, even if a request with an absolute URL does go back to the same webapp,
+ we are not propogating session identity either.</p>
+<p><b>Transparently map foreign context relative URLs to absolute URLs in "security
+ conscious" containers? No.</b></p>
+<p>If accessing a resource in a foreign context using a relative URL fails (security
+ conscious container that does not allow it), why not design the tag so it transparently
+ maps the foreign context relative URL to an absolute URL? </p>
+<p>We've decided against it because for the same reason as above, as well as for
+ portability concerns. In container X, the resource might be accessed via RequestDispatcher
+ and has therefore access to request attributes, the foreign context session
+ and application environment. However, if in container Y the resource is accessed
+ via a new HTTP request, the resource is not accessed with that same environment.</p>

+<h3>
+1. Introduction</h3>
+The <tt><forEach></tt> tag repeats its nested body content over the collection
+of objects defined by the <tt>items</tt> attribute. For example, the JSP code
+below creates an HTML table with one column that shows the default <i>display</i>
+value of each item in the collection.
+<pre> <table>
+ <c:forEach var="customer" items="$customers">
+ <tr><td><c:expr value="$customer"/></td></tr>
+ </c:forEach>
+ </table></pre>
+The <tt>forEach</tt> tag has the following features:
+<ul>
+<li>
+Supports all standard J2SE <a href="#items">collection types.</a></li>
+
+<li>
+Exports an object that holds the <a href="#currentItem">current item</a>
+of the iteration.</li>
+
+<li>
+Exports an object that holds information about the <a href="#status">status
+of the iteration.</a></li>
+
+<li>
+Supports <a href="#range">range attributes</a> to iterate over a subset
+of the original collection.</li>
+
+<li>
+Exposes an <a href="#IteratorTag">interface</a> as well as a <a href="#IteratorTagSupport">base
+implementation class</a> so developers can easily implement collaborating
+subtags as well their own iteration tags according to their specific needs.</li>
+</ul>
+The forEach tag is the <i>base</i> iteration tag. It handles the most common
+iteration cases conveniently. Other iteration tags are also provided in
+the stardard tag library to support specific, specialized functionality
+not handled by the <tt>forEach</tt> tag (e.g. the <tt>forTokens</tt> tag).
+Developers can also easily extend the behavior of this base iteration tag
+to customize it according to an application's specific needs.
+<h3>
+<a NAME="items"></a>2. Collection of objects to iterate over</h3>
+The <tt>forEach</tt> tag supports the following data types for the collection
+of objects to iterate over.
+<ul>
+ <li> Array of Java Objects</li>
+ <ul>
+ <li> If the array contains a set of primitive types, then the current item
+ for the iteration is automatically wrapped with its standard wrapper class
+ (e.g. <tt>Integer</tt> for <tt>int</tt>, <tt>Float</tt> for <tt>float</tt>,
+ etc...)</li>
+ </ul>
+ <li> Implementation of <tt>java.util.Collection</tt>. This includes among others:
+ <tt>List, LinkedList, ArrayList, Vector, Stack, Set.</tt></li>
+ <li> Implementation of <tt>java.util.Iterator</tt>.</li>
+ <ul>
+ <li> Use with caution. An <code>Iterator</code> object is not resettable so
+ it should not be used within more than one iteration tag.</li>
+ </ul>
+ <li> Implementation of <tt>java.util.Enumeration</tt>.
+ <ul>
+ <li>Use with caution. An <code>Enumeration</code> object is not resettable
+ so it should not be used within more than one iteration tag.</li>
+ </ul>
+ </li>
+ <li> Implementation of <tt>java.util.Map</tt>. This includes among others: <tt>HashMap,
+ Hashtable, Properties, Provider, Attributes. </tt>See below for additional
+ information about accessing the <a href="#currentItemMap">current item of
+ a Map</a>.</li>
+ <li> Implementation of <tt>java.sql.ResultSet</tt>, including <tt>javax.sql.RowSet</tt>.
+ See below for additional information about accessing the <a href="#currentItemResultSet">current
+ item of a ResultSet</a>.</li>
+ <li> String. The string represents a list of Comma Separated Values (e.g. "mon,tue,wed").</li>
+</ul>
+The <tt>items</tt> attribute is optional. If it is not specified, the <a href="#range">range
+attributes</a> must be specified to iterate a specific number of times over the
+tag's body.
+<h3>
+<a NAME="currentItem"></a>3. The current item</h3>
+<p>The current item of the iteration is made available via a JSP page scope attribute
+ defined with attribute <tt>var</tt>. Attribute var has nested visibility, i.e.
+ it only exists within the body of the <forEach> tag. At the end of the
+ tag, the attribute is removed (no prior value is restored). Attribute <tt>var</tt>
+ is optional. The page attribute is not created if a value is not defined for
+ <tt>var.</tt> </p>
+<p>Normally, each object exposed by the <tt>forEach</tt> tag is an item
+of the underlying collection being iterated over. However, if iterating
+over a <tt>Map </tt>or a<tt> ResultSet</tt>, the exposed object is as follows:
+<p><a NAME="currentItemMap"></a>If <tt>items</tt> is of type <tt>Map</tt>,
+then the current item will be of type <tt>Map.Entry</tt> which has the
+following two properties:
+<ul>
+<li>
+<tt>key</tt> - The key under which this item is stored in the underlying
+Map.</li>
+
+<li>
+<tt>value</tt> - The value that corresponds to this key.</li>
+</ul>
+So, to iterate over the values of a <tt>Hashtable</tt>, the code would
+be implemented as follows:
+<p><tt> <c:forEach var="entry" items="$myHashtable"/></tt> <br>
+ <tt> Next element is <c:expr value="$entry.value/></tt>
+ <br>
+ <tt> </c:forEach></tt>
+<p><a NAME="currentItemResultSet"></a>If items is of type <tt>ResultSet</tt>,
+ then the current item is the <tt>ResultSet</tt> object itself positioned at
+ the current row. Columns are accessed using the standard <tt>ResultSet</tt>
+ API.
+<h3>
+<a NAME="status"></a>5. Iteration Status</h3>
+The iterator tag also makes available a wealth of information relative to the
+iteration taking place. The set of properties supported by the status object is
+described <a href="#IteratorTagStatus">here</a>.
+<p>This status information is accessible by defining a JSP page scope attribute
+ via the <tt>status</tt> attribute. This page scope attribute has nested visibility,
+ i.e. it only exists within the body of the <forEach> tag. At the end of
+ the tag, the attribute is removed (no prior value is restored). This is an optional
+ attribute with no default. No page attribute is exposed if a value is not specified
+ for the<tt> status </tt>attribute.
+<p>In the example below, the JSP code creates an HTML table with the first
+column containing the position of the item in the collection, and the second
+containing the name of the employee.
+<pre> <table>
+ <c:forEach var="employee" items="$employees" status="status">
+ <tr>
+ <td><c:expr value="$status.count"/></td>
+ <td><c:expr value="$employee.name"/></td>
+ </tr>
+ </c:forEach>
+ </table></pre>
+
+<h3>
+<a NAME="range"></a>6. Range Attributes</h3>
+A set of range attributes is available to iterate on a subset of the collection
+of items. The <tt>begin</tt> and <tt>end</tt> indices can be specified,
+along with a <tt>step</tt>. If the <tt>items</tt> attribute is not specified,
+then the value of the current item is set to the integer value of the current
+index.
+<p>In this example, <tt>i</tt> would take values from 100 to 110 (included).
+<pre> <c:forEach var="i" begin="100" end="110">
+ <c:expr value="$i"/>
+ </c:forEach></pre>

+<h3>
+<a NAME="IteratorTag"></a>10. Tag Collaboration</h3>
+Custom tags give developers the power to provide added functionality to
+a JSP application without having the page author to use Java code.
+<p>In this example, a page author must handle an item of the iteration
+differently depending whether it is an odd or even element.
+<p><tt> <c:forEach var="product" items="products" status="status"><br>
+ <c:declare id="status" type="javax.servlet.jsp.jstl.core.IteratorTagStatus"/></tt><br>
+ <tt> <c-rt:choose></tt> <br>
+ <tt> <c-rt:when test="<%= status.getCount()
+ % 2 == 0 %>"></tt> <br>
+ <tt> <!-- even item --></tt> <br>
+ <tt> </c-rt:when></tt> <br>
+ <tt> <c-rt:otherwise></tt> <br>
+ <tt> <!-- odd item --></tt> <br>
+ <tt> </c-rt:otherwise></tt> <br>
+ <tt> </c-rt:choose></tt> <br>
+ <tt> </c:forEach></tt>
+<p>If this type of processing needs to be repeated often in the web applications
+of a company, it might be worth to provide page authors with a couple extra
+tags that would remove the need for conditional tags and expressions. For
+example:
+<p><tt> <c:forEach items="$products"></tt> <br>
+ <tt> <xyz:even></tt>
+<br><tt> <!-- even item --></tt>
+<br><tt> </xyz:even></tt>
+<br><tt> <xyz:odd></tt>
+<br><tt> <!-- odd item --></tt>
+<br><tt> </xyz:odd></tt>
+<br>
+ <tt> </c:forEach></tt>
+<p>In order to make this possible, tags like <tt><odd></tt> and <tt><even></tt>
+need to be able to get access to the information exported by the <tt>forEach</tt>
+tag. This could be done explicitely, by specifying the name of the status
+object exported by the forEach tag. For example:
+<p><tt> <c:forEach items="<%=products%>" <font color="#3366FF">status="status"</font>></tt>
+ <br>
+ <tt> <xyz:even <font color="#3366FF">iter="status"</font>></tt>
+<br><tt> <!-- even item --></tt>
+<br><tt> </xyz:even></tt>
+<br><tt> <xyz:odd <font color="#3366FF">iter="status"</font>></tt>
+<br><tt> <!-- odd item --></tt>
+<br><tt> </xyz:odd></tt>
+<br>
+ <tt> </c:forEach></tt>
+<p>The cooperation between these tags and the forEach tag can also be done
+implicitely via the <tt>findAncestorWithClass()</tt> method of the JSP
+API. This is possible because the <tt>forEach</tt> tag implements an interface
+that can be used in the call to <tt>findAncestorWithClass</tt> to get to
+the enclosing <tt>forEach</tt> tag.
+<p>The interface is defined as follows:<br>
+ <br>
+ <tt> interface IteratorTag {</tt> <br>
+ <tt> public Object getCurrent();</tt> <br>
+ <tt> public IteratorTagStatus getIteratorStatus();</tt> <br>
+ <tt> }</tt>
+<p>Interface <code>IteratorTagStatus</code> was described in a previous section.
+<p>
+The fact that the <tt>forEach</tt> tag exposes an interface also means
+that other tags with iterative behavior can be developed using the same
+interface and will collaborate in the same manner with nested tags. See
+class <tt>IteratorTagSupport</tt> below to make this process even easier.
+<h3>
+<a NAME="IteratorTagSupport"></a>11. Tag Extensibility</h3>
+The forEach tag provides iteration capabilities for the most common cases.
+A developer simply needs to expose an appropriate kind of object to take
+advantage of it.
+<p>However, there will be situations where more specialized functionality
+will be required. A developer may need to write a new tag to expose new
+controlling functionality (e.g. for traversal order of a deep data structure,
+custom filtering, selection of appropriate objects from a custom data source).
+This is why the <tt>IteratorTagSupport </tt>class is provided. It will
+facilitate the implementation of <i>specialized</i> iterator tags that
+will meet an application's specific requirements.
+<pre> public abstract class IteratorTagSupport {
+ ... (see source code)...
+ }</pre>
+JSTL itself uses this inheritance-based mechanism to support additional specialized
+iterator tags. For example, the <tt><forTokens></tt> tag is specialized to
+support string tokens. It leverages the iteration behavior implemented in <tt>IteratorTagSupport</tt>,
+and simply exposes a set of attributes that facilitate the specification of how
+tokens are derived from a <tt>String </tt>object.

+<h1>Overview</h1>
+<p>This document provides a high level overview of the JSP™ Standard Tag
+ Library (JSTL) as it stands for EA2 (Early Access release 2). If you have a
+ strong opinion on the topic — positive (you really like it), or constructive
+ (we messed up some parts and you have some constructive comments for improvements)
+ — we'll be happy to hear from you at <a href="mailto:jsr052-comments@sun.com">jsr052-comments@sun.com</a>.
+ All comments will be read but we cannot guaranteee personal replies to all of
+ them. </p>
+<p>Make sure you read this document first, then check out the jstl-examples web
+ application in the release (once you have installed it on your web container
+ following the instructions in the <a href="GettingStarted.html">Getting Started</a>
+ document). This will help you get a good feel for what JSTL is all about. Then
+ browse the other docs to get all the details, and finally give JSTL a ride in
+ your own <b>prototype</b> web application. You should use JSTL only in prototype
+ webapps because this is Early Access and things may/will change as we gather
+ feedback and make adjustments. Thanks for your help making JSTL an awesome standard
+ tag library...</p>
+<h3>Design Philosophy</h3>
+<p>JSP tag libraries help provide a clean separation between the business logic
+ and the presentation layer of web applications. By keeping the programming logic
+ out of JSP pages, web designers are now empowered to develop sophisticated JSP
+ pages without having to resort to the scripting language associated with their
+ JSP pages (usually the Java programming language). </p>
+<p>The base design philosophy in JSTL is therefore to provide page authors with
+ a script free environment. EA2 defines the foundation elements to make this
+ possible.</p>
+<h3>Multiple TLDs</h3>
+<p>A Tag Library is a collection of actions that encapsulate functionality to
+ be used from within a JSP page. JSTL includes a wide variety of actions that
+ naturally fit into discrete functional areas. This is why JSTL, altough a single
+ standard tag library, is exposed via multiple TLDs to clearly show the functional
+ areas it covers, as well as to give each one of them their own namespace. The
+ table below lists these functional areas along with their URI. The table also
+ shows the prefixes used in our documentation and examples (although web applications
+ can use any prefix they want).</p>
+<div align="center">
+ <table border="1" cellpadding="5">

+<h3><br>
+ Expression Language Support</h3>
+<p>A key contribution of JSTL is the integration of an Expression Language (EL).
+ An EL leverages the fact that JSP scoped attributes are the privileged way to
+ communicate information from the business logic to the JSP pages. It makes it
+ possible to easily access application data and manipulate it in simple ways
+ without having to use scriptlets or request-time expression values. </p>
+<p>For example, this conditional tag tests whether the country of a customer is
+ the USA.</p>
+<p><code> <c:if test="$customer.address.country == 'USA'"><br>
+ ...</code><br>
+ <code> </c:if></code></p>
+<p>There were quite a few issues involved with the support of an Expression Language
+ within JSTL given the constraint that it had to work without requiring any change
+ to the JSP spec. In order to be able to support both the scripting (rtexprvalues)
+ and the EL (elexprvalues) worlds, we had to come up with the concept of twin
+ tag libraries: one that supports the expression language, and one that supports
+ request time expression values. Our assumption is that people will mostly use
+ the EL-based tag libraries, while it is still possible for hard core scripting
+ page authors to use JSTL with rtexprvalues (provides benefits for type safety
+ and performance) via the request-time based tag libraries (their URI simply
+ has the "-rt" suffix appended).</p>
+<p>It is a hard task for the Expert Group to decide on a specific EL without first
+ getting the general feeling from the community. This is why JSTL currently
+ does not define a specific EL, but provides mechanisms for experimentation with
+ a variety of ELs. Tell us what you feel is important for that EL, and feel free
+ to implement one that others can experiment with. The goal is to select a single
+ EL once the JSTL spec is ready for Community Review.</p>
+<p>Early Access contains several candidate Expression Languages. One of them is
+ an implementation subset of ECMAScript (JavaScript) and is the one used by default.
+ You can read an <a href="@@@">overview of the ECMAScript subset of interest
+ for JSTL</a>.</p>
+<h3>Tag Collaboration</h3>
+<p>Tags usually collaborate with their environment in implicit and/or explicit
+ ways. Implicit collaboration is done via a well defined interface that allows
+ nested tags to work seamleasly with the ancestor tag exposing that interface.
+ The JSTL iterator tags support this mode of collaboration. Explicit collaboration
+ happens when a tag explicitely exposes information to its environment. Traditionally,
+ this has been done by exposing a scripting variable (with a JSP scoped attribute
+ providing the actual object). Because JSTL supports an expression language,
+ the need for scripting variables is significantly reduced. This is why all the
+ JSTL tags expose information only as JSP scoped attributes (no scripting variable
+ exposed). A bold move, we agree, but we feel this is the proper design decision
+ to support script-free JSP pages. </p>
+<p>The convention is to use the name "var" for any tag attribute that
+ exports information about the tag. For example, an iterator tag exposes the
+ current item of the collection it is iterating over in the following way:</p>
+<p><code> <c:forEach var="customer" items="$customers"></code><code><br>
+ ...</code><br>
+ <code> </c:forEach></code></p>
+<p>It is important to note that a name different than "id" was selected
+ to stress the fact that a variable is exposed (actually a JSP scoped attribute),
+ but not a scripting variable (which is normally the case when using an attribute
+ named "id").</p>
+<p>The convention also establishes the attribute "scope" to set the
+ scope (page, request, session, application) of the JSP scoped attribute.</p>
+<p>In situations where a tag exposes more than one piece of information, the name
+ "var" is used for the primary piece of information being exported,
+ and an appropriate name is selected for any other secondary piece of information
+ exposed (e.g. an iteration current status information is exported by the foreach
+ tag via attribute <code>status</code>.)</p>
+<p>The fact that JSTL tags do not expose scripting variables would make it hard
+ to collaborate with other tags whose data must be passed as rtexprvalues. To
+ that effect, tag <declare> allows to declare a scripting variable to be
+ associated with the JSP scoped attribute of the same name.</p>
+<h3>Tag Overloading</h3>
+<p>In JSTL, we try as much as possible to avoid too much "overloading"
+ of a tag; i.e. tags with lots of attributes that can do just about anything.
+ Rather, we privilege a larger number of tags with well focused behavior.</p>

+ </tt></h2>
+<hr width="100%" noshade>
+<h3>1. Introduction</h3>
+<p>The core set of XML tags provides the basic functionality to easily parse and
+ access XML data. Another important piece of functionality is the ability to
+ iterate over elements in an XML document, as well as conditionally process JSP
+ code fragments depending on the result of an XPath expression. The actions presented
+ in this document provide these capabilities.</p>
+<h3>2. <forEach></h3>
+<p>The <forEach> action evaluates the given XPath expression and iterates
+ over the result, setting the context node to each element in the iteration.
+ For example:</p>
+<blockquote>
+ <p><code><x:forEach select="$doc//author"><br>
+ <x:valueOf select="@name"><br>
+ </x:forEach> </code></p>
+</blockquote>
+<p>Optional attribute "var" makes it possible to save the current context
+ node of the iteration in a JSP "page" attribute. The exported object
+ has nested visibility. It is illegal to specify any scope other than "page"
+ for "var".</p>
+<h3>3. <tt><if></tt></h3>
+<p>The <tt><if></tt> action has a "select" attribute that specifies
+ an XPath expression. The expression is evaluated and the resulting object is
+ converted to a boolean according to the <a href="#XpathBooleanFunction">semantics
+ of the XPath boolean function</a>. The tag renders its body if the result is
+ true. For example:</p>
+<blockquote>
+ <p><code><x:if select="$customer/[location='UK']"><br>
+ UK based<br>
+ </x:if></code>
+</blockquote>
+<h3>4. <tt><choose> <when> <otherwise></tt></h3>
+<p>The <tt><choose></tt> action selects one among a number of possible alternatives.
+ It consists of a sequence of <x:when> elements followed by an optional
+ <x:otherwise>. Each <x:when> element has a single attribute, select,
+ which specifies an XPath expression. When a <x:choose> element is processed,
+ each of the <x:when> elements has its expression evaluated in turn, and
+ the resulting object is converted to a boolean according to the <a href="#XpathBooleanFunction">semantics
+ of the XPath boolean function</a>. The body of the first, and only the first,
+ <x:when> whose result is true is rendered. </p>
+<p>If none of the test conditions of nested <tt><when></tt> tags evaluates
+ to true, then the body of an <tt><otherwise></tt> tag is evaluated, if present.
+</p>
+<blockquote>
+ <p><code><x:choose><br>
+ <x:when test="$customer/firstName"><br>
+ Hello <xtags:valueOf select="$customer/firstName"/><br>
+ </x:when><br>
+ <x:otherwise><br>
+ Hello there friend<br>
+ </x:otherwise><br>
+ </x:choose></code></p>
+</blockquote>
+<h3><a name="XpathBooleanFunction"></a>5. XPath "boolean" function</h3>
+<p>As specified in the XPath spec, the boolean function converts its arguments
+ to a boolean as follows:</p>
+<ul>
+ <li>a number is true if an only if it is neither positive or negative zero nor
+ NaN</li>
+ <li>a node-set is true if and only if it is non-empty</li>
+ <li>a string is true if and only if its lenght is non-zero</li>
+</ul>

+<h3>1. Introduction</h3>
+<p>Enterprise data used in the web tier is increasingly XML these days —
+ whether the enterprise data is a response coming from a Web Service, the result
+ of a stock quote from Nasdaq, a google search, babel fish translation, an Amazon
+ book search, NewsML news articles, or RSS for content syndication. When companies
+ cooperate over the web, XML is the data format of choice for exchanging information.<br>
+</p>
+<p>XML is therefore becoming more and more important in a page author's life.
+ The set of XML tags specified in JSTL is therefore meant to address the basic
+ XML needs a page author is likely to encounter.</p>
+<h4>XPath</h4>
+<p>A key aspect of dealing with XML documents is to be able to easily access their
+ content. <a href="http://www.w3.org/TR/xpath">XPath</a>, a W3C recommendation
+ since 1999, provides an easy notation for specifying and selecting parts of
+ an XML document. The XML tagset in JSTL is therefore based on XPath.</p>
+<p>For the <i>XPath challenged</i>, here are a few links to get you started quickly:</p>
+<ul>
+ <li><a href="http://www.zvon.org/xxl/XPathTutorial/General/examples.html">Zvon
+ XPath Tutorial</a></li>
+ <li><a href="http://www.oreilly.com/catalog/xmlnut/chapter/ch09.html">XML in
+ a Nutshell — Chapter 9 — XPath</a></li>
+</ul>
+<p>It is important to note that the Expert Group is still debating which <i>global</i>
+ Expression Language(s) will be officially supported by JSTL. While this discussion
+ is still taking place, the approach we've taken here is to consider XPath as
+ a <i>local</i> Expression Language that applies to the XML tagset. How this
+ local XPath Expression Language integrates with the Global Expression Language
+ as well as JSP.next is briefly discussed in this document. </p>
+<p>The assumption is that if XPath (or a derivative) is not selected as <i>the</i>
+ or one of <i>the</i> Global Expression Languages, this set of tags would probably
+ stay as is. If XPath were to become one of <i>the</i> Global ELs, the design
+ of these tags would probably change, the extent of which has not yet been addressed.<br>
+</p>
+<h3>2. XPath as a <i>local</i> Expression Language for the XML set of tags</h3>
+<p>What we're doing with our set of XML tags is expanding our notion of Expression
+ Language so it can also apply "locally" to tags that want to support
+ an EL that is not <i>the</i> global one(s) supported within JSTL.</p>
+<p>Below are the rules of integration that XPath follows as a <i>local</i> EL,
+ so we have the guarantees that it plays nicely within the JSP/JSTL environment.</p>
+<h4>XPath Context</h4>
+ In XPath, the context for evaluating an expression consists of::
+<ul>
+ <li> a node or nodeset (see below)</li>
+ <li>variable bindings (see below)</li>
+ <li>function library: the default function library comes with the XPath engine.
+ Some engines provide extension functions or allow customization to add new
+ functions. The XPath function library in JSTL is limited to the core function
+ library of the XPath specification.</li>
+ <li>namespace prefix definitions which allow namespace prefixes to be used within
+ the XPath expression<br>
+ ( e.g. /SOAP-ENV:Envelope/SOAP-ENV:Body/m:foo)</li>
+</ul>
+<p><b>Attributes to specify XPath Expressions</b></p>
+<p>In the JSTL set of XML tags, XPath expressions are always specified using
+ attribute "select". This therefore means that only values specified
+ for "select" attributes are evaluated using the XPath expression language.
+ All other attributes are evaluated using the rules associated with the currently
+ active global Expression Language. This should help avoid confusion between
+ XPath and the global Expression Language.</p>
+<p><b>XPath Variable Bindings</b></p>
+<p>JSTL supports variables in XPath expressions. The mapping of XPath variable
+ expressions is defined as follows:<p>
+<table border="1" cellpadding="2" cellspacing="1">
+ <tr>
+ <td><code>$foo</code></td>
+ <td>maps to <code>pageContext.findAttribute("foo")</code></td>
+ </tr>
+ <tr>
+ <td><code>$page:foo</code></td>
+ <td>maps to page scope</td>
+ </tr>
+ <tr>
+ <td><code>$request:foo</code></td>
+ <td>maps to request scope</td>
+ </tr>
+ <tr>
+ <td><code>$session:foo</code></td>
+ <td>maps to session scope</td>
+ </tr>
+ <tr>
+ <td><code>$app:foo</code></td>
+ <td>maps to application scope</td>
+ </tr>
+ <tr>
+ <td><code>$param:foo</code></td>
+ <td>maps to <code>request.getParameter("foo")</code></td>
+ </tr>
+ <tr>
+ <td><code>$initParam:foo</code></td>
+ <td>maps to <code>request.getInitParameter("foo")</code></td>
+ </tr>
+ <tr>
+ <td><code>$cookie:foo</code></td>
+ <td>maps to the cookie's value for name <code>foo</code></td>
+ </tr>
+ <tr>
+ <td><code>$header:foo</code></td>
+ <td>maps to <code>request.getHeader("foo")</code></td>
+ </tr>
+</table>
+<p>Through these mappings, scoped attributes, parameters, headers, and cookies
+ can all be used inside XPath expressions easily. For example:
+<blockquote>
+ <p> <code>/foo/bar[@x=$param:name]</code></p>
+</blockquote>
+<p> would find the "bar" element with an attribute "x" equal
+ to the value of the http request parameter "name".<br>
+</p>
+<p><b>Context Setup</b></p>
+<p>The context for the evaluation of an XPath Expression can be set in one of
+ two ways; either directly within the XPath expression:</p>
+<blockquote>
+ <p><code><x:parse source="$xml" var="doc"/><br>
+ <x:expr select="$doc/..."/></code></p>
+</blockquote>
+<p>or via an ancestor tag that sets a context that can be applied to its nested
+ tags. In the example below, the XPath expression specified in the select attribute
+ of <expr> has its context set to the current "atom" node in
+ the document.</p>
+<blockquote>
+ <p><code><x:forEach select="$doc//atom"/><br>
+ <x:expr select="name"/><br>
+ <x:forEach/> </code></p>
+</blockquote>
+<h4>Relationship between Local EL and the Global EL(s)</h4>
+<p>As mentioned in the previous section, only the "select" attribute
+ of xml tags can take XPath expressions. Global EL expressions and XPath expressions
+ cannot be mixed in the "select" attributes. </p>
+<p>With JSTL 1.0, the xml tagset knows that the value of select attributes are
+ XPath expressions. However, things will be different in JSP.next when the evaluation
+ of 'elexprvalues' are handled directly by the container. If the metacharacter
+ used to identify an 'elexprvalue' is defined as '$', this means that XPath expressions
+ starting with a variable would have to be escaped in a JSP.next environment,
+ unless JSP.next has provisions in the TLD to prevent expression evaluation.</p>
+<p>There might be other issues. These will be addressed once the discussions on
+ the Expression Language resume.</p>
+<h3>3. <parse></h3>
+<p>The <parse> action parses an XML document and saves the resulting object
+ in the JSP scoped attribute specified by attribute "var". The type
+ of the resulting object is not defined by the spec to allow implementations
+ to use whatever they deem best for efficient implementations of the XML tagset.</p>
+<p>The XML document can be specified either via the "source" attribute
+ (String or Reader object) </p>
+<blockquote>
+ <pre><jc:import url="http://acme.com/athletes?country=ethiopia" var="xml"/><br><x:parse source="$xml" var="athletes"/></pre>
+</blockquote>
+<p>or inline via the tag's body content:</p>
+<blockquote>
+ <pre><x:parse var="athletes">
+ <athletes>
+ <athlete>
+ <name>Abebe Bikila</name>
+ <country>Ethiopa</country><br> </athlete>
+ <athlete>
+ <name>Mamo Wolde</name>
+ <country>Ethiopia</country><br> </athlete>
+ </athletes>
+</x:parse>
+</pre>
+</blockquote>
+<p> When used in conjunction with the <parse> tag, the JSTL core tag <import>
+ provides access to a wide variety of URL-based input resources representing
+ XML documents.</p>
+<h4>Performance</h4>
+<p> If an implementation of the XML tagset is based on DOM-like structures (check
+ with the specific implementation you're using), there will be a significant
+ performance impact when dealing with large XML documents. To help with this,
+ attribute "filter" can be used to allow filtering of the input data
+ prior to having it parsed by the implementation into a DOM-like structure. </p>
+<p>For example, if one is interested in processing only the "European"
+ customers which represent only 10% of the original XML document received as
+ input, it will greatly reduce the size and complexity of the resulting DOM structure
+ if all non-European customers are pruned from the XML document prior to parsing.
+</p>
+<pre> <jc:import url="http://acme.com/customers" var="xml"/><br> <x:parse source="$xml" filter="$filterEuropeanCust" var="doc"/></pre>
+<p>The "filter" attribute accepts an object of type <code>org.xml.sax.XMLFilter</code>.</p>
+<p>If configuration of the filter is desirable, it is suggested that the developer
+ of the filter provide a custom tag for easy configuration by a page author.</p>
+<blockquote>
+ <p> <code><acme:myFilter var="filter" xpath="//author"
+ ... /><br>
+ <x:parse filter="$filter" .../></code></p>
+</blockquote>
+<h3>4. <expr></h3>
+<p>The <tt><expr></tt> action evaluates the given XPath expression on the current
+ context node and outputs the result of the evaluation to the current JspWriter
+ object. It is the equivalent of <tt><%= %></tt> and <code><jc:expr></code>,
+ with the difference that it is meant for the XPath Expression Language world
+ (as opposed to the scripting language world (<code><%= %></code>) and
+ the Global Expression Language world of JSTL <code><jc:expr></code>).
+</p>
+<p>The expression to be evaluated is specified via the attribute "select"
+ and must be in the XPath syntax. The result of the evaluation is coerced to
+ a String and is subsequently emitted into the current JspWriter object. </p>
+<p>For example: </p>
+<p><tt> <x:expr select="$athletes/athlete/name"/></tt> </p>
+<h3>5. <set></h3>
+<p>The <tt><set></tt> action evaluates an XPath expression (attribute "select")
+ and sets the result into a JSP scoped attribute specified by attribute "var".
+</p>
+<p>In this first example, the list of athletes from a specific country is saved
+ in scoped attribute athletesOfCountry:</p>
+<blockquote> <code><x:set select="$athletes/athlete[country=$request:country]"
+ var="athletesOfCountry"/>
+ </code></blockquote>
+<p>In this second example, the <set> action is used to set a context used
+ by other xml tags:</p>
+<blockquote>
+ <pre><x:set select="$athletes/athlete[id=$param:athleteId]" var="ath"/>
+
+<x:expr select="$ath/name"/><br><x:expr select="$ath/country"/></pre>
+</blockquote>
+<h3>6. Notes</h3>
+<ul>
+ <li>
+ <p>Some XPath expressions can be evaluated without a context<br>
+ For example:<br>
+ <code>starts-with($header:user-agent,
+ 'Mozilla 4.0')</code></p>
+ </li>
+</ul>

+ If the source attribute is not specified, the input XML document is read from the
+ tag's body content. </p>
+<p>In the example below, the XML document to be transformed is retrieved from
+ an http request, while the XSLT stylesheet for the transformation is a webapp
+ resource. The result of the transformation is written to the page.</p>
+<pre> <c:import url="http://acme.com/customers?country=usa" var="xml"/>
+ <c:import url="/WEB-INF/xslt/customerList.xsl" var="xslt"/><br> <x:transform source="$xml" xslt="$xslt"/></pre>
+<p>The source and xslt attributes are objects of any of the following types: java.lang.String,
+ java.io.Reader, or javax.xml.transform.Source.</p>
+<p>As seen in the example above, the result of the transformation is written to
+ the page by default. It is also possible to capture the result of the transformation
+ in two other ways:</p>
+<ul>
+ <li>into a javax.xml.transform.Result object specified via attribute "result"
+ (object to be provided by page author)</li>
+ <li>into a org.w3c.dom.Document object, that will be stored in the JSP scope
+ attribute specified by "var". </li>
+</ul>
+<p>"var" and "result" are mutually exclusive. What's interesting
+ with the "var" attribute is that the exported document can be used
+ directly with the other xml tags. For example:</p>
+<blockquote>
+ <p><code><x:transform source="..." xslt=".." var="doc/><br>
+ <x:expr select="$doc/..."/></code></p>
+</blockquote>
+<p>The <transform> action also supports attribute "transformer"
+ described in section 3 (<transformer>) below.</p>
+<h3>2. <param></h3>
+<p>The <param> subtag can be used along with <transform> to set transformation
+ parameters. Attributes 'name' and 'value' are used to specify the parameter.
+ The value attribute is optional. If it is not specified the value is retrieved
+ from the tag's body.</p>
+<p>For example:</p>
+<pre> <x:transform source="$xml" xslt="$xslt"><br> <x:param name="foo" value="foo-value"/><br> </x:transform></pre>
+<h3>3. <transformer></h3>
+<p>It is sometimes the case that the same stylesheet transformation needs to be
+ applied multiple times to different source XML documents. A more efficient approach
+ is to process the transformation stylesheet once, and then save this "transformer"
+ object for successive transformations.</p>
+<p>As shown in the example below, the <transformer> tag can be used in collaboration
+ with the transformer attribute of <transform> to efficiently reuse a transformation
+ stylesheet.</p>
+<pre> <c:import url="/xslt/style.xsl" var="xslt"/><br> <x:transformer xslt="$xslt" var="transformer"/><br> <c:forEach items="$xmlDocs" var="xml"><br> ...<br> <x:transform source="$xml" transformer="$transformer" /><br> ...<br> </c:forEach></pre>
+The attribute xslt is optional. If not specified, the stylesheet is read from
+the tag's body content.

+<h1>SPEL Implementation</h1>
+<h4>Nathan Abramson (arista@atg.com)</h4>
+
+<h2>Overview</h2>
+
+<p>This distribution contains an implementation of the <a
+href="spel.html">Simplest Possible Expression Language (SPEL) for the
+JSTL</a>. In addition to the implementation, the distribution
+contains regression tests for the parser and evaluator, and a simple
+performance test.
+
+<p>The distribution contains the following directories and files:
+
+<ul>
+<li><b>doc/</b> - documentation
+<li><b>src/</b> - all source files
+<li><b>lib/classes.jar</b> - compiled classes
+</ul>
+
+<h2>Implementation Notes</h2>
+
+<ul>
+
+<li>The class files are found in the package
+<b>org.apache.taglibs.standard.lang.spel</b>.
+
+<li>The class implementing ExpressionEvaluator is
+<b>org.apache.taglibs.standard.lang.spel.Evaluator</b>
+
+<li>The implementation assumes that the ExpressionEvaluator interface
+is found at <b>javax.servlet.jsp.jstl.core.ExpressionEvaluator</b>, with the
+following definition (taken from Shawn's implementation):
+
+<ul><pre>
+public String validate(String attributeName,
+ String expression);
+public Object evaluate(String attributeName,
+ String expression,
+ Class expectedType,
+ Tag tag,
+ PageContext pageContext)
+ throws JspException;
+</pre></ul>
+
+<p>If this is not the package or definition of the ExpressionEvaluator
+interface, the appropriate changes should be made to the <a
+href="../src/org.apache.taglibs.standard/lang/spel/Evaluator.java">src/org/apache/taglibs/jsptl/lang/spel/Evaluator.java</a>
+source file. In any case, the <a
+href="../src/javax/servlet/jsptl/ExpressionEvaluator.java">ExpressionEvaluator
+implementation</a> should be removed from the distribution, and the
+distribution should be compiled against the "real" implementation of
+that class.
+
+<li>The parser was generated using <a
+href="http://www.webgain.com/products/metamata/java_doc.html">JavaCC</a>.
+The parser definition is found in <a
+href="../src/org.apache.taglibs.standard/lang/spel/SpelParser.jj">src/org/apache/taglibs/jsptl/lang/spel/SpelParser.jj</a>,
+and all files generated by JavaCC are placed into the
+org.apache.taglibs.standard.lang.spel.parser package. Note that JavaCC is not
+required to compile the SPEL implementation - it is only needed if the
+grammar in the SpelParser.jj file changes.
+
+<li>JavaCC 1.0 was used to generate the parser. If desired, the most
+recent version of JavaCC can be used to regenerate the parser, but the
+<a href="#regressionTests">regression tests</a> should then be run to
+make sure the behavior hasn't changed.
+
+<li>All localizable error messages are stored in the <a
+href="../src/org.apache.taglibs.standard/lang/spel/Resources.properties">src/org/apache/taglibs/jsptl/lang/spel/Resources.properties</a>
+file. This file must be copied into the final distribution with the
+generated class files.
+
+</ul>
+
+<a name="regressionTests"><h2>Regression Tests</h2></a>
+
+<p>There are two sets of automated regression tests - the first tests
+the parser, and the second tests the full evaluator. In both cases,
+the tester takes an input file containing expressions to be parsed or
+evaluated, processes each expression, and writes the results or errors
+to an output file. The output file can then be compared against an
+expected output file to see if any regression has occurred.
+
+<p>In both cases, input lines that are blank or start with "#" are
+copied to the output file without interpretation. This allows
+comments to appear in the output file, which can aid in debugging.
+
+<h4>Parser tests</h4>
+
+<p>The parser test input file is found at <a
+href="../src/org.apache.taglibs.standard/lang/spel/test/parserTests.txt">src/org/apache/taglibs/jsptl/lang/spel/test/parserTests.txt</a>.
+Each line represents an expression to be parsed - the expression is
+parsed, and printed back out in the evaluator's "canonical form". For
+example, in the canonical form, all Strings are enclosed by double
+quotes, all names are prefixed by a scope operator ":", etc.
+
+<p>The expected outputs are found at <a
+href="../src/org.apache.taglibs.standard/lang/spel/test/parserTestsExpectedOutput.txt">src/org/apache/taglibs/jsptl/lang/spel/test/parserTestsExpectedOutput.txt</a>
+
+<p>The parser tests can be run like this:
+
+<ul><pre>
+java org.apache.taglibs.standard.lang.spel.test.ParserTest {inputFile} {outputFile} [{expectedOutputFile}]
+</pre></ul>
+
+The {expectedOutputFile} is optional - if supplied, the test will
+compare the ouput file with the expected output file and print whether
+the test passed or failed.
+
+<h4>Evaluation tests</h4>
+
+<p>For the evaluation test, a "dummy" PageContext was created
+containing some beans with properties in various scopes. That
+PageContext is created in the "createTestContext" method of <a
+href="../src/org.apache.taglibs.standard/lang/spel/test/EvaluationTest.java">src/org/apache/taglibs/jsptl/lang/spel/test/EvaluationTest.java</a>.
+
+<p>The evaluation test input file is found at <a
+href="../src/org.apache.taglibs.standard/lang/spel/test/evaluationTests.txt">src/org/apache/taglibs/jsptl/lang/spel/test/evaluationTests.txt</a>.
+Each line represents an expression to be parsed, followed by a line
+specifying the expected type - the expression is parsed, and the
+resulting value is printed along with its class.
+
+<p>The expected outputs are found at <a
+href="../src/org.apache.taglibs.standard/lang/spel/test/evaluationTestsExpectedOutput.txt">src/org/apache/taglibs/jsptl/lang/spel/test/evaluationTestsExpectedOutput.txt</a>
+
+<p>The evaluation tests can be run like this:
+
+<ul><pre>
+java org.apache.taglibs.standard.lang.spel.test.EvaluationTest {inputFile} {outputFile} [{expectedOutputFile}]
+</pre></ul>
+
+The {expectedOutputFile} is optional - if supplied, the test will
+compare the ouput file with the expected output file and print whether
+the test passed or failed.
+
+<a name="optimizations"><h2>Optimizations</h2></a>
+
+<p>Because expression evaluation could conceivably make up a large
+portion of a JSP's rendering time, a great deal of emphasis was placed
+on performance. The following performance optimizations were used:
+
+<ul>
+
+<p><li>Parsed expressions are cached, so that each expression is
+parsed only once. To avoid synchronization bottlenecks, the cache is
+only synchronized around determining if an expression is in the cache,
+and putting a parsed expression into the cache. This means that two
+threads could both end up parsing and caching the same uncached
+expression at the same time, but the result of this is harmless. This
+caching happens in the Evaluator class.
+
+<p><li>The Evaluator class is also responsible for parsing literals
+(expressions not starting with "$"). The results of these parsings
+are also cached, but in this case the key is {expression,
+expectedType}. Rather than creating an actual key class (which would
+require object creations for each lookup), the tuple key is simulated
+by having two levels of caches: expected type -> expression -> parsed
+expression.
+
+<p><li>The mapping from {class,propertyName} to PropertyDescriptor is
+cached by the BeanInfoManager. The PropertyDescriptors are used by
+the "{bean}.{property}" construct.
+
+<p><li>In cases where a primitive type needs to be wrapped in an
+object (such as the final casting from expression result to expected
+type), the PrimitiveObjects class is used to do the wrapping. This
+class precalculates the wrappings for bytes and chars with values from
+0-255, and shorts, ints, and longs with values from -1000 to 1000.
+Wrapped values in those ranges will not require any object creations
+to represent their primitive values.
+
+</ul>
+
+<a name="performanceTests"><h2>Performance Tests</h2></a>
+
+<p>The distribution includes a single performance test which evaluates
+an expression many times. The expression is:
+
+<ul><pre>
+session:bean1a.bean1.int1 < 24
+</pre></ul>
+
+<p>To test for synchronization bottlenecks, the test spawns several
+threads which simultaneously evaluate the expression many times.
+
+<p>The test then runs again, but evaluates the expression "by hand"
+using direct API calls - i.e.,
+pageContext.getAttribute(...).getBean1().getInt1 () < 24. So the
+performance test essentially determines the cost of using an
+expression instead of an rtexprvalue.
+
+<p>The test is run like this:
+
+<ul><pre>
+org.apache.taglibs.standard.lang.spel.test.PerformanceTest {#threads} {#iterations/thread}
+</pre></ul>
+
+<p>The initial results are encouraging - running 20 threads over
+100000 iterations/thread, a ThinkPad 600E could do ~50000
+iterations/second using the evaluator, and ~110000 iterations/second
+using the API calls. So using the API calls in this example is only
+twice as fast as using the evaluator, which means that the expression
+language introduces a significant, but not severe performance penalty.

+<h1>Simplest Possible Expression Language (SPEL) for JSPSTL</h1>
+<h4>Nathan Abramson (arista@atg.com)</h4>
+
+<h2>Overview</h2>
+
+<p>The SPEL is designed to be the simplest possible JSPSTL expression
+language that is still useful. The only required features of the SPEL
+are:
+
+<ul>
+
+<li>notion of scope (page, request, session, app)
+<li>nested attributes
+<li>relational operators
+
+</ul>
+
+<p>The idea is to design a language that will eventually grow, keeping
+in mind that future versions of the language should be backwards
+compatible with this version of the SPEL.
+
+<h2>Syntax</h2>
+
+<p>The syntax is extremely simple. Attributes are accessed by name,
+with an optional scope ("page:", "request:", "session:", "app:").
+Properties of attributes are accessed using the "." operator, and may
+be nested arbitrarily. Attribute and property names must be java
+identifiers, unless they are quoted. Relational comparisons are
+allowed using the relational operators (==, !=, <, >, <=,
+>=). Comparisons may be made against other values, or against
+boolean, String, integer, or floating point literals.
+
+<p>The following are the constructs supported by the SPEL:
+
+<table>
+

+<td><b>Expression</b></td>
+<td>::=</td>
+<td><b>Value</b></td>

+<p>Notes:
+
+<ul>
+
+<li>An identifier is constrained to be a Java identifier - i.e., no
+"-", no "/", etc. without quoting. Eventually this may be expanded,
+but this is the minimum.
+
+<li>A String only recognizes a limited set of escape sequences, and \
+may not appear unescaped. This may eventually be expanded, but once
+again, this is the minimum.
+
+<li>The definitions for integer and floating point literal are pretty
+much taken from the Java definitions.
+
+<li>The relational operator for equality is "==" (double equals).
+This is to be more Java-like, but is it the best idea?
+
+<li>There are no logical operators (and, or, not). Designing these
+introduces the notion of grouping (parentheses) and order of
+precedence, and also deciding what the actual operators should be (and
+vs. &&), which also introduces the notion of reserved words.
+It is possible that keeping these out severely limits the usefulness
+of the language. Should they be introduced?
+
+</ul>
+
+<h2>Reservered Words</h2>
+
+<p>The following words are reserved for the language and should not be
+used as identifiers without being quoted.
+
+<ul><table>
+<tr valign="top">
+
+<td><pre>
+and
+or
+not
+</pre></td>
+
+<td> </td>
+
+<td><pre>
+eq
+ne
+lt
+</pre></td>
+
+<td> </td>
+
+<td><pre>
+gt
+le
+ge
+</pre></td>
+
+<td> </td>
+
+<td><pre>
+true
+false
+null
+</pre></td>
+
+<td> </td>
+
+<td><pre>
+instanceof
+</pre></td>
+
+</tr>
+</table></ul>
+
+<p>Note that these words may not be in the language now, but they may
+be in the future, so developers should avoid using these words now.
+
+<h2>Named Values</h2>
+
+<p>If a named value is specified with a scope of "page", "request",
+"session", or "app", its value is the value of that name in the given
+scope. If no scope is given, the value is found according to the
+rules of PageContext.findAttribute(name).
+
+<p>If a named value is specified with a scope of "header", its value
+is obtained by calling HttpServletRequest.getHeader(String).
+
+<p>If a named value is specified with a scope of "param", its value is
+obtained by calling ServletRequest.getParameter(String).
+
+<p>If a named value is specified with a scope of "paramvalues", its
+value is obtained by calling
+ServletRequest.getParameterValues(String).
+
+<p>In any of these cases, if a value is not found, the result is an <a
+href="#expressionExceptions">ExpressionException</a>, not "null".
+
+<h2>Property Values</h2>
+
+<p>The expression "value . propertyName" denotes a property
+expression. The property is found through introspection by treating
+the value as a JavaBean and calling the appropriate setter method. If
+the result is a primitive value, the result is converted to the Object
+equivalent of the primitive.
+
+<ul>
+
+<li>It is an error if the bean value is null.
+
+<li>It is an error if the specified property is not found in the bean.
+
+<li>It is an error if calling the getter results in an error.
+
+</ul>
+
+<p>Note that these error conditions might be relaxed in the future,
+but for now they are as strict as possible.
+
+<p>In the future, the "." operator might be extended to interpret
+other name/value collections, such as Maps, but for now this is not
+the case. Note that in the future, the "Map behavior" might happen
+automatically, so JavaBeans should avoid implementing "java.util.Map"
+to avoid having their behavior change in the future.
+
+<h2>Type Conversion</h2>
+
+<p>Every expression is evaluated in the context of an "expected type".
+The result of the expression evaluation may not match the expected
+type exactly, so the following rules are applied:
+
+<ul>
+
+<li>If the expected type is assignable from the value's type, no
+conversion is required.
+
+<li>If the expected type is an Object type and the value is null, no
+conversion is required.
+
+<li>If the expected type is a primitive and the value is null, an
+error results.
+
+<li>If the expected type is a primitive and the value is the Object
+equivalent of that primitive, the Object equivalent is returned.
+
+<li>If the expected type (or its Object equivalent) is a numeric type,
+and the value is also a numeric type, the value is converted to the
+expected type, even if loss of precision would occur. The numeric
+types are: byte, short, int, long, float, double.
+
+<li>Any other condition is an error
+
+</ul>
+
+<h2>Relational Comparisons</h2>
+
+<p>The following rules are applied to evaluate a relational
+comparison.
+
+<h3>Rules for == and !=</h3>
+
+<p>The rules for equality are as follows:
+
+<ul>
+
+<li>If both values are null, the values are considered to be equal
+
+<li>If only one value is null, the values are not equal
+
+<li>If both values are the same object, the values are considered to
+be equal
+
+<li>If both values are numeric types, then the value with the least
+precise type is "cast up" to the type of the other value, and their
+values are compared. The order of numeric types from least precise to
+most precise is byte, short, int, long, float, double
+
+<li>If leftHandValue.equals(rightHandValue), the values are considered
+to be equal
+
+<li>In all other cases, the values are not equal
+
+</ul>
+
+<h3>Rules for >, <, >=, <=</h3>
+
+<p>The rules for ordered comparisons are as follows:
+
+<ul>
+
+<li>If both values are Strings, the Strings are comapared according to
+the rules of String.compareTo(String).
+
+<li>If both values are numeric types, then the value with the least
+precise type is "cast up" to the type of the other value, and their
+values are compared. The order of numeric types from least precise to
+most precise is byte, short, int, long, float, double
+
+<li>All other cases result in an error
+
+</ul>
+
+<a name="expressionExceptions"><h2>ExpressionExceptions</h2></a>
+
+<p>The ExpressionException mechanism in the JSTL is provided as a way
+for expression languages to indicate that there was a problem
+evaluating an expression, but the problem was small enough that a
+default value could be substituted in its place without invoking the
+entire JSP error handling mechanism.
+
+<p>The SPEL throws javax.servlet.jsp.jstl.core.ExpressionException in the
+following situations:
+
+<ul>
+
+<li>A NamedValue (e.g., "session:profile") can't be found. If the
+specified name is not found in the specified scope, then an
+ExpressionException is thrown, not a null value.
+
+<li>A requested property of a bean can't be evaluated, either because:
+
+<ul>
+
+<li>the bean's value is null
+
+<li>the bean does not have the specified property
+
+<li>the bean's property is not readable
+
+<li>there is an error invoking the bean's read method
+
+</ul>
+
+</ul>
+
+<h2>Literals and Delimiter</h2>
+
+<p>The SPEL is responsible for handling both expressions and
+literals. Expressions begin with a "$" character. For example:
+
+<ul><pre>
+<mytags:if test="$bean1.a < 3" />
+</pre></ul>
+
+<p>Any value that does not begin with "$" is treated as a literal that
+is parsed to the expected type using the PropertyEditor for the
+expected type:
+
+<ul><pre>
+<mytags:if test="true" />
+</pre></ul>
+
+<p>There may be literal values that start with the "$" character. If
+that is the case, the value must be escaped using the "\" character.:
+
+<ul><pre>
+<mytags:price price="\$3.95" />
+</pre></ul>
+
+<p>If a value starts with "\$", it is treated as a literal value with
+the leading "\" removed.

+<p>JSTL exposes in its API the abstract class ConditionalTagSupport to facilitate
+ the implementation of custom conditional tags that leverage the standard conditional
+ behavior defined in JSTL. This example shows custom tag <usCustomer> that returns true if
+its customer attribute value points to a US customer.
+ It can be used both in the context of a simple conditional execution, as well
+ as in the context of a mutually conditional execution by exposing the result
+ of the conditional execution in a JSP page attribute via the tag attribute 'var'.

+<h3>Array Access</h3>
+
+<p>EcmaScript uses the [] notation to access array elements. If the first operand is an array then the second operand (the one that goes between the brackets) should be an expression that evaluates to an integer. If the first operand is a reference to an object then the second operand should be an expression that evaluates to a string that names a property of the object.
+
+<p>Here is an example:</p>
+
+<h4>Favorite Actor and Role</h4>
+
+<% request.setAttribute("myArray", new String[] {"Harrison", "Ford", "Indiana", "Jones"}); %>
+
+<table border="1">
+ <tr>
+ <th>Array Index</th>

+<h3>Property Access</h3>
+
+<p>EcmaScript uses the dot (.) notation to access elements of an object. The . operator expects an object as its left operand and the name of an object property as its right operand. The right operand should not be a string or a variable that contains a string but should be the literal name of the property without quotes.</p>

+<p>Here is an example:</p>

+<% request.setAttribute("myDate", new Date()); %>

+<h3>String Support</h3>
+
+<p>The EcmaScript String object type has methods for operating on string values. Many of these methods simply make a copy of the string with HTML tags added before and after. Other methods can extract a character or substring or serach for a character in a substring. Here are examples of a few of these methods</p>

+<h1>Welcome to the jsptl-examples web application!</h1>
+<p>This web application includes a variety of sample JSP pages that showcase the
+ JSTL tags currently being specified within the <a href="http://www.jcp.org/jsr/detail/52.jsp">JSR-052
+ Expert Group</a>.
+<p><b>WARNING: This is EARLY ACCESS (EA). The goal of this EA program is to keep
+ the community informed of the EG's progress as well as to give the community
+ a chance to experiment with the standard tag library (JSTL) early in the specification
+ process so that valuable feedback can quickly be channelled back to the Expert
+ Group.</b>
+<h3>Documentation</h3>
+<p>Documentation on the JSTL tags is available at <a href="http://jakarta.apache.org/taglibs/doc/jsptl-doc">http://jakarta.apache.org/taglibs/doc/jsptl-doc</a>.
+ It is also available as the jsptl-docs web application of the jsptl EA2 release.
+<h3>Mailing Lists</h3>
+<p>There are three ways to obtain information from or send your comments to the
+ JSR052 Expert Group:
+<ol>
+ <li><b>Support</b>: For support/usage questions, please use the <a href="mailto:taglibs-user@jakarta.apache.org">user
+ mailing list</a> of jakarta-taglibs. </li>
+ <li><b>Development</b>: For bugs, development related questions, please use
+ the <a href="mailto:taglibs-dev@jakarta.apache.org">developer mailing list</a>
+ of jakarta-taglibs</li>
+ <li><b>Comments to the JSR052 EG</b>: To provide the Expert Group with feedback
+ on the JSTL, use either the <a href="mailto:taglibs-dev@jakarta.apache.org">developers
+ mailing list</a> at Jakarta, or you may contact the expert group privately
+ at <a href="mailto:jsr052-comments@sun.com">jsr052-comments@sun.com</a>. All
+ comments will be read, but we cannot guarantee a personal reply to all messages
+ received.</li>
+</ol>
+<h3>Examples</h3>
+<p>The JSTL examples have been divided in the following category:</p>
+<ul>
+ <li><a href="iterators/index.html">Iterator Tags</a> (<forEach>, <forToken>)</li>
+ <li><a href="conditionals/index.html">Conditional Tags</a> (<if>, <choose>)</li>
+ <li><a href="elsupport/index.html">Expression Language Support Tags</a> (<expr>,
+ <set>, <define>)</li>
+ <li><a href="misc/index.html">Miscellaneous</a> (various tests)</li>
+ <li><a href="ecmascript/index.html">EcmaScript Examples</a> (examples showcasing some of EcmaScript's features)</li>
+</ul>
+<p>The navigation bar at the top of each index page provides quick navigation
+ to each set of example pages.</p>
+<p>When navigating the examples, the following icons will allow you to look at
+ the source code as well as execute the example JSP page.</p>
+<table border="1" align="center" cellpadding="10">
+ <tr>
+ <td width="30"><img src="images/code.gif"></td>
+ <td>Look at the source code of the example JSP page</td>
+ </tr>
+ <tr>
+ <td width="30"><img src="images/execute.gif"></td>
+ <td>Execute the example JSP page</td>
+ </tr>
+</table>
+<h3>Infrastructure</h3>
+<p>The source code for the JSTL examples includes class <code>startup.Init</code>
+ to initilialize the objects used in the examples. This allows us to mimic the
+ environment that would normally be used within an MVC architecture: the Controller
+ invokes the business logic, saves the objects required by the web application
+ into JSP scoped attributes (usually request), and then invokes the proper JSP
+ page. For the sake of this "examples" webapp, all objects are saved
+ in the application scope.</p>
+<p>The application attributes are:</p>
+<ul>
+ <li><code>customers</code><br>
+ A collection of Customer objects</li>
+ <li><code>intArray</code><br>
+ An array of int's</li>
+ <li><code>stringArray</code><br>
+ An array of Strings</li>
+ <li><code>numberMap</code><br>
+ A Map instance associating Integer objects with their Spanish names</li>
+ <li><code>enum</code><br>
+ An enumeration on numberMap from above.<br>
+ </li>
+</ul>
+<p>The classes of interest that hold the information manipulated by the JSP pages
+ are:</p>
+<ul>
+ <li>Customer
+ <ul>
+ <li>int key</li>
+ <li>String lastName</li>
+ <li>String firstName</li>
+ <li>Date birthDate</li>
+ <li>Address address<br>
+ <br>
+ </li>
+ </ul>
+ </li>
+ <li>Address
+ <ul>
+ <li>String line1</li>
+ <li>String line2</li>
+ <li>String city</li>
+ <li>String state</li>
+ <li>String country</li>
+ </ul>
+ </li>

+<h2>Iterator Tags Examples</h2>
+<h3>Simple <a href="../ShowSource.jsp?filename=/iterators/Simple.jsp"><img src="../images/code.gif" width="24" height="24" border="0"></a>
+ <a href="Simple.jsp"><img src="../images/execute.gif" width="24" height="24" border="0"></a>
+</h3>
+Simply displays the default <code>toString()</code> value of the items in the
+<code>Customers</code> collection.<br>
+<h3> Range <a href="../ShowSource.jsp?filename=/iterators/SimpleRange.jsp"><img src="../images/code.gif" width="24" height="24" onMouseDown="MM_callJS('showJspCode(\"Simple2.jsp\")')" border="0"></a>
+ <a href="SimpleRange.jsp"><img src="../images/execute.gif" width="24" height="24" border="0"></a>
+</h3>
+<p>Another simple example. Similar to the previous one, except that in this case
+ there is no collection to iterate over. The <code>items</code> attribute is
+ optional in the <code><forEach></code> tag. When it is not specified,
+ the range attributes must be used to iterate a specific number of times over
+ the tag's body. In this example, we simply iterate over the integer values specified
+ by the range attributes.</p>
+<h3>Data Types <a href="../ShowSource.jsp?filename=/iterators/DataTypes.jsp"><img src="../images/code.gif" width="24" height="24" onMouseDown="MM_callJS('showJspCode(\"Simple2.jsp\")')" border="0"></a> <a href="DataTypes.jsp"><img src="../images/execute.gif" width="24" height="24" border="0"></a></h3>
+<p>The <code><forEach></code> tag supports a large number of data types
+ for the collection of objects to iterate over. In this example, we feature the
+ following data types: array of primitives, array of objects, Enumeration, Properties
+ (Map), String (Comma Separated Values).</p>
+<h3>Iteration Status <a href="../ShowSource.jsp?filename=/iterators/Status.jsp"><img src="../images/code.gif" width="24" height="24" onMouseDown="MM_callJS('showJspCode(\"Simple2.jsp\")')" border="0"></a> <a href="Status.jsp"><img src="../images/execute.gif" width="24" height="24" border="0"></a></h3>
+<p>The iterator tag exposes a wealth of information relative to the iteration
+ taking place. This example features some of that status information.</p>
+<h3>Collaboration <a href="../ShowSource.jsp?filename=/iterators/Collaboration.jsp"><img src="../images/code.gif" width="24" height="24" onMouseDown="MM_callJS('showJspCode(\"Simple2.jsp\")')" border="0"></a> <a href="Collaboration.jsp"><img src="../images/execute.gif" width="24" height="24" border="0"></a></h3>
+<p>The iterator tags expose interface IteratorTag to allow custom tags to establish
+ implicit collaboration. This example shows two custom tags, <even> and
+ <odd> who take advantage of this implicit collaboration.</p>
+<h3><forTokens> <a href="../ShowSource.jsp?filename=/iterators/ForTokens.jsp"><img src="../images/code.gif" width="24" height="24" onMouseDown="MM_callJS('showJspCode(\"Simple2.jsp\")')" border="0"></a> <a href="ForTokens.jsp"><img src="../images/execute.gif" width="24" height="24" border="0"></a></h3>
+<p>The <forEach> tag provides the basic iteration capabilities. <forTokens>
+ is a specialization for the handling of Strings of tokens. Essentially the same
+ as <forEach>, except that it only applies to Strings of tokens and that
+ it has an extra attribute "delims" to specify the token delimiter.</p>
+<h3>Extensibility (ToBeDone)</h3>
+<p>JSTL exposes in its API the abstract class IteratorTagSupport to facilitate
+ the implementation of custom iterator tags that leverage the standard iteration
+ behavior defined in JSTL. This example shows a custom iterator tag that ...</p>

+
+ <p>The <a href="http://www.jcp.org/jsr/detail/52.jsp">JSR-052 Expert Group</a>,
+ operating under the Java Community Process, will be hosting the
+ reference implementation of the JSP Standard Tag Library (JSTL) at
+ Jakarta Taglibs. JSTL is not finalized yet, but early-access releases
+ are currently available.
+ </p>
+
+ <p><b>NOTE:</b> JSTL requires a JSP container that supports
+ the Java Servlet 2.3 and JavaServer Pages 1.2 specifications.
+ Jakarta <a href="http://jakarta.apache.org/tomcat/">
+ Tomcat 4</a> supports the new specifications.
+ </p>
+
+ <p><b>IMPORTANT:</b> This release of JSTL is an early-access release and
+ does not represent a standard of any kind. The API and implementation are
+ subject to change in the future. The major purpose of this release is to
+ provide early information to the community of JSP developers about the
+ direction and scope of JSTL. Community feedback is actively sought; if
+ you have any comments, please email us at
+ <a href="mailto:jsr052-comments@sun.com">jsr052-comments@sun.com</a>.
