your web application.</li>
<li><code>struts-xxxxx.tld</code> - The tag library descriptor files
for the Struts 1.0 tag libraries (bean, html, logic, and
template). You must place these files in the <code>/WEB-INF</code>
directory of your web application, and reference them with
appropriate <code>&lt;taglib&gt;</code> directives in your
web.xml file. <strong>NOTE</strong> - The struts-form.tld
file is deprecated; you should use the struts-html.tld file
instead.</li>
<li><code>jdbc2_0-stdext.jar</code> - The JDBC 2.0 Optional Package
API classes (package <code>javax.sql</code>). You will need to

applications by your servlet container.</li>
<li><code>struts-config_1_0.dtd</code> - The document type descriptor
(DTD) for the Struts configuration file (which is typically named
<code>/WEB-INF/struts-config.xml</code>. Your configuration file
will be validated against an internal copy of this DTD -- this

release APIs. Usage of these files and APIs is deprecated, and they
will be removed from releases after Struts 1.0:</p>
<ul>
<li><code>lib/</code> - Directory containing files you will need in
your own applications. The individual files of interest are:
<ul>
<li><code>struts.jar</code> - JAR file that contains the compiled
Java classes for both version 0.5 and 1.0 of Struts. You must
place this file in the <code>/WEB-INF/lib</code> directory of
your web application.</li>
<li><code>struts.tld</code> - The tag library descriptor file for
the 0.5 version of the Struts tags. You must place this file
in the <code>/WEB-INF</code> directory of your web application,
and reference it with appropriate <code>&lt;taglib&gt;</code>
directives in your web.xml file.</li>
</ul></li>
</ul>
</section>
<section name="What's New?" href="New">
<p><strong>DEPRECATIONS</strong> - The entire custom tag library
that is documented in <code>struts.tld</code> has been deprecated.
These tags correspond to the Struts 0.5 functionality that is also
deprecated, and have been replaced (and considerably enhanced) in
the various individual tag libraries.</p>
<p><strong>DEPRECATIONS</strong> - The entire custom tag library
that is documented in <code>struts-form.tld</code> has been deprecated
because this library has been renamed <code>struts-html.tld</code>
instead.</p>
<p><strong>DEPRECATIONS</strong> - Several classes in the
<code>org.apache.struts.util</code> package have been marked as
deprecated in their entirety, because they will be replaced by
versions from the Jakarta Commons project once those packages are
released. These deprecated classes will <strong>not</strong> be
removed until a release after Struts 1.1. In general, the only
change required inside user code using these classes will be to
update the <code>import</code> statement. The following classes
are involved:</p>
<ul>
<li>ArrayStack</li>
<li>BeanUtils</li>
<li>ConvertUtils</li>
<li>FastArrayList</li>
<li>FastHashMap</li>
<li>FastTreeMap</li>
<li>GenericConnection</li>
<li>GenericDataSource</li>
<li>PropertyUtils</li>
</ul>
<p>The following new features have been added to the basic controller
framework (package <code>org.apache.struts.action</code>):</p>
<p>The following new features have been added to the utility classes
(package <code>org.apache.struts.util</code>):</p>
<ul>
<li><code>GenericDataSource</code> can now be configured with a "ping"
type command (via the <code>pingCommand</code> and
<code>pingQuery</code> properties) that will be executed before
returning a connection from <code>getConnection()</code>. This
can be used to detect stale connections due to timeouts or a
database server restart. If the ping command fails, the corresponding
connection will be thrown away, and a new one allocated.</li>
</ul>
<p>The following new features have been added to the
<em>struts-html</em> custom tag library (package
<code>org.apache.struts.taglib.html</code>):</p>
<ul>
<li>It is now possible to use any object in the values and labels
collections for the <code>&lt;html:options&gt;</code> tag.</li>
<li>Added the missing <code>tabindex</code> attribute to the
<code>&lt;html:radio&gt;</code> tag.</li>
<li>On the <code>&lt;html:img&gt;</code>, <code>&lt;html:link&gt;</code>,
and <code>&lt;html:rewrite&gt;</code> tags, you can now specify
arbitrary object values in the <code>Map</code> used to include
dynamic request attributes, as long as the <code>toString()</code>
method renders the values appropriately.</li>
<li>In all cases where "minimized" attributes were being generated
(<code>checked</code>, <code>disabled</code>, <code>multiple</code>,
<code>readonly</code>, and <code>selected</code>), the generated
attribute has a value (such as <code>selected="true"</code>) for
XML syntax compatibility.</li>
</ul>
<p>The following new features have been added to the
<em>struts-logic</em> custom tag library (package
<code>org.apache.struts.taglib.logic</code>):</p>
<p>The following new features have been added to the
<em>struts-template</em> custom tag library (package
<code>org.apache.struts.taglib.template</code>):</p>
<p>The following new features have been added to the Struts Documentation
application (and corresponding contents on the Struts web site):</p>

<section name="Changes and Bug Fixes" href="Changes">
<p>The following changes and bug fixes have occurred in the configuration
files related to Struts:</p>
<ul>

ENTITY declaration for the <code>Location</code> element.</li>
<li>The DTD for version 2.3 web application deployment descriptors has
been updated to the most recent (Proposed Final Draft 2) version.</li>
</ul>
<p>The following changes and bug fixes have occurred in the basic
controller framework (package <code>org.apache.struts.action</code>):</p>
<p>The following changes and bug fixes have occurred in the utilities
(package <code>org.apache.struts.util</code>):</p>
<ul>
<li>The <code>FastArrayMap()</code>, <code>FastHashMap()</code>, and
<code>FastTreeMap()</code> classes not correctly implement the
<code>clone()</code>, <code>equals()</code>, and
<code>hashCode()</code> methods consistent with the requirements
of the Java standard Collections APIs.</li>
<li><code>PropertyUtils</code> can now access public methods defined
in nested interfaces.</li>
<li>A misleading error message returned by <code>BeanUtils</code>
has been corrected.</li>
<li>Work around a problem compiling the <code>FastXxxxx</code> classes

private class named <code>Iterator</code>.</li>
<li>Remove a JDK 1.3 dependency that prevented compiling
<code>BeanUtils</code> under JDK 1.2.</li>
<li>Generate "&amp;amp;" instead of "&amp;" in query strings that
contain more than one name/value pair.</li>

<p>The following changes and bug fixes have occurred in the
<em>struts-html</em> custom tag library (package
<code>org.apache.struts.taglib.html</code>):</p>
<ul>
<li>Restore the ability of the <code>&lt;html:button&gt;</code> tag to
retrieve the button text from the nested body content (so that it
can be easily internationalized).</li>

attribute of an <code>&lt;html:options&gt;</code> tag is invalid,
report the correct property name in the error message.</li>

occurred:</p>
<ul>
<li>Fix a reference to an old Struts 0.5 tag in one of the User's Guide
examples.</li>
<li>Fix the stylesheet used to transform XML into HTML documentation so
that nested <code>&lt;body&gt;</code> tags are not created.</li>
<li>The DTD for Struts configuration files has been refined to highlight
the fact that you should use <code>&lt;set-property&gt;</code>
elements to configure your data source implementation.</li>
