<h2><a name="introduction">Introduction</a></h2>
<p>Ant provides a number of optional tasks for developing 1.x and 2.x
<a href="http://java.sun.com/products/ejb" target="_top">Enterprise Java Beans (EJBs)</a>.
In general these tasks are specific to the particular vendor's EJB Server.</p>
<p> The tasks support:<br>
<ul>
<li><a href="http://www.borland.com">Borland </a>
Application Server 4.5</li>
<li><a href="http://www.iplanet.com">iPlanet </a>
Application Server 6.0</li>
<li><a href="http://www.jboss.org/" target="_top">
JBoss 2.1</a> and above EJB servers</li>
<li><a href="http://www.bea.com" target="_top">Weblogic</a>
4.5.1 through to 7.0 EJB servers</li>
<li><a href="http://www.objectweb.org/jonas/" target="_top">JOnAS</a>
2.4.x and 2.5 Open Source EJB server</li>
<li><a href="http://www.ibm.com/websphere">IBM WebSphere</a> 4.0</li>
</ul>
Vendors such as BEA and IBM now provide custom Ant tasks to work with their
particular products. More importantly, EJB3.0 renders this whole process obsolete.
Accordingly, developement of these tasks is effectively frozen. Bug reports
and especially patches are welcome, but there is no pressing need to add
support for new application servers. Nobody should be writing new EJB2.x applications
and definitely not new EJB2.x servers.

<h2><a name="ddcreator">ddcreator</a></h2>
<h3><b>Description:</b></h3>
<p>ddcreator will compile a set of Weblogic text-based deployment descriptors into a serialized
EJB deployment descriptor. The selection of which of the text-based descriptors are to be compiled
is based on the standard Ant include and exclude selection mechanisms.

<h2><a name="ejbc">ejbc</a></h2>
<h3><b>Description:</b></h3>
<p>The ejbc task will run Weblogic's ejbc tool. This tool will take a serialized deployment descriptor,
examine the various EJB interfaces and bean classes and then generate the required support classes
necessary to deploy the bean in a Weblogic EJB container. This will include the RMI stubs and skeletons
as well as the classes which implement the bean's home and remote interfaces.</p>
<p>
The ant task which runs this tool is able to compile several beans in a single operation. The beans to be
compiled are selected by including their serialized deployment descriptors. The standard ant
<code>include</code> and <code>exclude</code> constructs can be used to select the deployment descriptors
to be included. </p>
<p>
Each descriptor is examined to determine whether the generated classes are out of date and need to be
regenerated. The deployment descriptor is de-serialized to discover the home, remote and
implementation classes. The corresponding source files are determined and checked to see their
modification times. These times and the modification time of the serialized descriptor itself are
compared with the modification time of the generated classes. If the generated classes are not present
or are out of date, the ejbc tool is run to generate new versions.</p>

<h2>
<a NAME="iplanet-ejbc"></a>iplanet-ejbc</h2>
<h3>
<b>Description:</b></h3>
Task to compile EJB stubs and skeletons for the iPlanet Application Server
6.0. Given a standard EJB 1.1 XML descriptor as well as an iAS-specific
EJB descriptor, this task will generate the stubs and skeletons required
to deploy the EJB to iAS. Since the XML descriptors can include multiple
EJBs, this is a convenient way of specifying many EJBs in a single Ant
task.
<p>For each EJB specified, the task will locate the three classes that
comprise the EJB in the destination directory. If these class files
cannot be located in the destination directory, the task will fail. The
task will also attempt to locate the EJB stubs and skeletons in this directory.
If found, the timestamps on the stubs and skeletons will be checked to
ensure they are up to date. Only if these files cannot be found or if they
are out of date will the iAS ejbc utility be called to generate new stubs
and skeletons.</p>

<h2><a name="ejbjar">ejbjar</a></h2>
<h3><b>Description:</b></h3>
<p>This task is designed to support building of EJB jar files (EJB 1.1 &amp; 2.0).
Support is currently provided for 'vanilla' EJB jar files - i.e. those containing only
the user generated class files and the standard deployment descriptor. Nested
elements provide support for vendor specific deployment tools. These currently
include: </p>
<ul>
<li>Borland Application Server 4.5</li>
<li>iPlanet Application Server 6.0</li>
<li>JBoss 2.1 and above</li>
<li>Weblogic 5.1/6.0 session/entity beans using the weblogic.ejbc tool</li>
<li>IBM WebSphere 4.0</li>
<li>TOPLink for WebLogic 2.5.1-enabled entity beans</li>
<li><a href="http://www.objectweb.org/jonas/">JOnAS</a> 2.4.x and 2.5 Open Source EJB server</li>
</ul>
<p>The task works as a directory scanning task, and performs an action for each
deployment descriptor found. As such the includes and excludes should be set
to ensure that all desired EJB descriptors are found, but no application
server descriptors are found. For each descriptor found, ejbjar will parse the
deployment descriptor to determine the necessary class files which implement the
bean. These files are assembled along with the deployment descriptors into a
well formed EJB jar file. Any support files which need to be included in the
generated jar can be added with the <code>&lt;support&gt;</code> nested element. For each
class included in the jar, ejbjar will scan for any super classes or super
interfaces. These will be added to the generated jar.</p>
<p>If no nested vendor-specific deployment elements are present, the task will
simply generate a generic EJB jar. Such jars are typically used as the input to
vendor-specific deployment tools. For each nested deployment element, a vendor
specific deployment tool is run to generate a jar file ready for deployment in
that vendor's EJB container. </p>
<p>The jar files are only built if they are out of date. Each deployment tool
element will examine its target jar file and determine if it is out of date with
respect to the class files and deployment descriptors that make up the bean. If
any of these files are newer than the jar file the jar will be rebuilt otherwise
a message is logged that the jar file is up to date.</p>
<p>The task uses the
<a href="http://jakarta.apache.org/bcel"> jakarta-BCEL </a> framework
to extract all dependent classes. This
means that, in addition to the classes that are mentioned in the
deployment descriptor, any classes that these depend on are also
automatically included in the jar file.</p>
<h3>Naming Convention</h3>
Ejbjar handles the processing of multiple beans, and it uses a set of naming
conventions to determine the name of the generated EJB jars. The naming convention
that is used is controlled by the &quot;naming&quot; attribute. It supports the
following values
<ul>
<li>descriptor</li>
<p>This is the default naming scheme. The name of the generated bean is derived from the
name of the deployment descriptor. For an Account bean, for example, the deployment
descriptor would be named <code>Account-ejb-jar.xml</code>. Vendor specific descriptors are
located using the same naming convention. The weblogic bean, for example, would be named
<code>Account-weblogic-ejb-jar.xml</code>. Under this arrangement, the deployment descriptors
can be separated from the code implementing the beans, which can be useful when the same bean code
is deployed in separate beans.
</p>
<p>This scheme is useful when you are using one bean per EJB jar and where you may be
deploying the same bean classes in different beans, with different deployment characteristics.
<li>ejb-name</li>
<p> This naming scheme uses the <code>&lt;ejb-name&gt;</code> element from the deployment descriptor to
determine the bean name. In this situation, the descriptors normally use the generic
descriptor names, such as <code>ejb-jar.xml</code> along with any associated vendor specific descriptor
names. For example, If the value of the <code>&lt;ejb-name&gt;</code> were to be given in the deployment descriptor
as follows:
<pre>
&lt;ejb-jar&gt;
&lt;enterprise-beans&gt;
&lt;entity&gt;
&lt;ejb-name&gt;Sample&lt;/ejb-name&gt;
&lt;home&gt;org.apache.ant.ejbsample.SampleHome&lt;/home&gt;
</pre>
then the name of the generated bean would be <code>Sample.jar</code>
</p>
<p> This scheme is useful where you want to use the standard deployment descriptor names, which may be more
compatible with other EJB tools. This scheme must have one bean per jar.
</p>
<li>directory</li>
<p>
In this mode, the name of the generated bean jar is derived from the directory
containing the deployment descriptors. Again the deployment descriptors typically use
the standard filenames. For example, if the path to the deployment descriptor is
<code>/home/user/dev/appserver/dd/sample</code>, then the generated
bean will be named <code>sample.jar</code>
</p>
<p>
This scheme is also useful when you want to use standard style descriptor names. It is often
most useful when the descriptors are located in the same directory as the bean source code,
although that is not mandatory. This scheme can handle multiple beans per jar.
</p>
<li>basejarname</li>
<p>
The final scheme supported by the <code>&lt;ejbjar&gt;</code> task is used when you want to specify the generated
bean jar name directly. In this case the name of the generated jar is specified by the
&quot;basejarname&quot; attribute. Since all generated beans will have the same name, this task should
be only used when each descriptor is in its own directory.
</p>
<p>
This scheme is most appropriate when you are using multiple beans per jar and only process a single
deployment descriptor. You typically want to specify the name of the jar and not derive it from the
beans in the jar.
</p>
</ul>
<a name="ejbjar_deps"><h3>Dependencies</h3></a>
<p>In addition to the bean classes, ejbjar is able to ad additional classes to the generated
ejbjar. These classes are typically the support classes which are used by the bean's classes or as
parameters to the bean's methods.</p>
<p>In versions of Ant prior to 1.5, ejbjar used reflection and attempted to add the super
classes and super interfaces of the bean classes. For this technique to work the bean
classes had to be loaded into Ant's JVM. This was not always possible due to class dependencies.
</p>
<p>The ejbjar task in Ant releases 1.5 and later uses the
<a href="http://jakarta.apache.org/bcel"> jakarta-BCEL </a> library
to analyze the bean's class
files directly, rather than loading them into the JVM. This also allows ejbjar to add all
of the required support classes for a bean and not just super classes.
</p>
<p>In Ant 1.5, a new attribute, <code>dependency</code> has been introduced to allow the
buildfile to control what additional classes are added to the generated jar. It takes three
possible values</p>
<ul>
<li><code>none</code> - only the bean classes and interfaces described in the bean's
descriptor are added to the jar.</li>
<li><code>super</code> - this is the default value and replicates the original ejbjar
behaviour where super classes and super interfaces are added to the jar</li>
<li><code>full</code> - In this mode all classes used by the bean's classes and interfaces
are added to the jar</li>
</ul>
<p>The <code>super</code> and <code>full</code> values require the
<a href="http://jakarta.apache.org/bcel"> jakarta-BCEL </a> library
to be available. If it is not, ejbjar will drop back to the behaviour corresponding to
the value <code>none</code>.</p>

<h3>Nested Elements</h3>
<p>In addition to the vendor specific nested elements, the ejbjar task provides
three nested elements. </p>
<h4>Classpath</h4>
<p>The <code>&lt;classpath&gt;</code> nested element allows the classpath
to be set. It is useful when setting the classpath from a reference path. In all
other respects the behaviour is the same as the classpath attribute.</p>
<a name="ejbjar-dtd"><h4>dtd</h4></a>
<p>The <code>&lt;dtd&gt;</code> element is used to specify the local location of DTDs to be
used when parsing the EJB deployment descriptor. Using a local DTD is much
faster than loading the DTD across the net. If you are running ejbjar behind a
firewall you may not even be able to access the remote DTD. The supported
vendor-specific nested elements know the location of the required DTDs within
the vendor class hierarchy and, in general, this means <code>&lt;dtd&gt;</code> elements are
not required. It does mean, however, that the vendor's class hierarchy must be
available in the classpath when Ant is started. If your want to run Ant without
requiring the vendor classes in the classpath, you would need to use a
<code>&lt;dtd&gt;</code> element.</p>
<table border="1" cellpadding="2" cellspacing="0">
<tr>
<td valign="top"><b>Attribute</b></td>
<td valign="top"><b>Description</b></td>
<td align="center" valign="top"><b>Required</b></td>
</tr>
<tr>
<td valign="top">publicId</td>
<td valign="top">The public Id of the DTD for which the location is being provided</td>
<td align="center" valign="top">Yes</td>
</tr>
<tr>
<td valign="top">location</td>
<td valign="top">The location of the local copy of the DTD. This can either be a
file or a resource loadable from the classpath.</td>
<td align="center" valign="top">Yes</td>
</tr>
</table>
<h4>support</h4>
<p>The <code>&lt;support&gt;</code> nested element is used to supply additional classes
(files) to be included in the generated jars. The <code>&lt;support&gt;</code> element is a
<a href="../CoreTypes/fileset.html">FileSet</a>, so it can either reference a fileset declared elsewhere or it can be
defined in-place with the appropriate <code>&lt;include&gt;</code> and <code>&lt;exclude&gt;</code> nested
elements. The files in the support fileset are added into the generated EJB jar
in the same relative location as their location within the support fileset. Note
that when ejbjar generates more than one jar file, the support files are added
to each one.</p>
<h3>Vendor-specific deployment elements</h3>
Each vendor-specific nested element controls the generation of a deployable jar
specific to that vendor's EJB container. The parameters for each supported
deployment element are detailed here.
<h3><a name="ejbjar_jboss">Jboss element</a></h3>
<p>The jboss element searches for the JBoss specific deployment descriptors and adds them
to the final ejb jar file. JBoss has two deployment descriptors:
<ul><li>jboss.xml</li>
<li>for container manager persistence:<br>
<table border="1">
<tr><td><b>CMP version</b></td><td><b>File name</b></td></tr>
<tr><td>CMP 1.0</td><td>jaws.xml</td></tr>
<tr><td>CMP 2.0</td><td>jbosscmp-jdbc.xml</td></tr>
</table>
</li>
</ul>
<br>
. The JBoss server uses hot deployment and does
not require compilation of additional stubs and skeletons.</p>

<h3><a name="ejbjar_weblogic">Weblogic element</a></h3>
<p>The weblogic element is used to control the weblogic.ejbc compiler for
generating weblogic EJB jars. Prior to Ant 1.3, the method of locating CMP
descriptors was to use the ejbjar naming convention. So if your ejb-jar was
called, Customer-ejb-jar.xml, your weblogic descriptor was called Customer-
weblogic-ejb-jar.xml and your CMP descriptor had to be Customer-weblogic-cmp-
rdbms-jar.xml. In addition, the <code>&lt;type-storage&gt;</code> element in the weblogic
descriptor had to be set to the standard name META-INF/weblogic-cmp-rdbms-
jar.xml, as that is where the CMP descriptor was mapped to in the generated
jar.</p>
<p>There are a few problems with this scheme. It does not allow for more than
one CMP descriptor to be defined in a jar and it is not compatible with the
deployment descriptors generated by some tools.</p>
<p>In Ant 1.3, ejbjar parses the weblogic deployment descriptor to discover the
CMP descriptors, which are then included automatically. This behaviour is
controlled by the newCMP attribute. Note that if you move to the new method of
determining CMP descriptors, you will need to update your weblogic deployment
descriptor's <code>&lt;type-storage&gt;</code> element. In the above example, you would
define this as META-INF/Customer-weblogic-cmp-rdbms-jar.xml.</p>

<p>The weblogic nested element supports three nested elements. The
first two, <code>&lt;classpath&gt;</code> and <code>&lt;wlclasspath&gt;</code>, are used to set the
respective classpaths. These nested elements are useful when setting up
class paths using reference Ids. The last, <code>&lt;sysproperty&gt;</code>, allows
Java system properties to be set during the compiler run. This turns out
to be necessary for supporting CMP EJB compilation in all environments.

<h3><a name="ejbjar_websphere">WebSphere element</a></h3>
<p>The websphere element searches for the websphere specific deployment descriptors and
adds them to the final ejb jar file. Websphere has two specific descriptors for session
beans:
<ul>
<li>ibm-ejb-jar-bnd.xmi</li>
<li>ibm-ejb-jar-ext.xmi</li>
</ul>
and another two for container managed entity beans:
<ul>
<li>Map.mapxmi</li>
<li>Schema.dbxmi</li>
</ul>
In terms of WebSphere, the generation of container code and stubs is called <code>deployment</code>.
This step can be performed by the websphere element as part of the jar generation process. If the
switch <code>ejbdeploy</code> is on, the ejbdeploy tool from the websphere toolset is called for
every ejb-jar. Unfortunately, this step only works, if you use the ibm jdk. Otherwise, the rmic
(called by ejbdeploy) throws a ClassFormatError. Be sure to switch ejbdeploy off, if run ant with
sun jdk.
</p>
<p>
For the websphere element to work, you have to provide a complete classpath, that contains all
classes, that are required to reflect the bean classes. For ejbdeploy to work, you must also provide
the classpath of the ejbdeploy tool and set the <i>websphere.home</i> property (look at the examples below).

<h3><a name="ejbjar_iplanet">iPlanet Application Server (iAS) element</a></h3>
The &lt;iplanet&lt; nested element is used to build iAS-specific stubs and
skeletons and construct a JAR file which may be deployed to the iPlanet
Application Server 6.0. The build process will always determine if
the EJB stubs/skeletons and the EJB-JAR file are up to date, and it will
do the minimum amount of work required.
<p>Like the WebLogic element, a naming convention for the EJB descriptors
is most commonly used to specify the name for the completed JAR file.
For example, if the EJB descriptor ejb/Account-ejb-jar.xml is found in
the descriptor directory, the iplanet element will search for an iAS-specific
EJB descriptor file named ejb/Account-ias-ejb-jar.xml (if it isn't found,
the task will fail) and a JAR file named ejb/Account.jar will be written
in the destination directory. Note that when the EJB descriptors
are added to the JAR file, they are automatically renamed META-INF/ejb-jar.xml
and META-INF/ias-ejb-jar.xml.</p>
<p>Of course, this naming behaviour can be modified by specifying attributes
in the ejbjar task (for example, basejarname, basenameterminator, and flatdestdir)
as well as the iplanet element (for example, suffix). Refer to the
appropriate documentation for more details.</p>

<p>As noted above, the iplanet element supports additional <code>&lt;classpath&gt;</code>
nested elements.</p>
<h3>
Examples</h3>
This example demonstrates the typical use of the <code>&lt;iplanet&gt;</code> nested element.
It will name each EJB-JAR using the "basename" prepended to each standard
EJB descriptor. For example, if the descriptor named "Account-ejb-jar.xml"
is processed, the EJB-JAR will be named "Account.jar"
<pre>
&lt;ejbjar srcdir="${build.classesdir}"
descriptordir="${src}"&gt;
&lt;iplanet destdir="${assemble.ejbjar}"
classpath="${ias.ejbc.cpath}"/&gt;
&lt;include name="**/*-ejb-jar.xml"/&gt;
&lt;exclude name="**/*ias-*.xml"/&gt;
&lt;/ejbjar&gt;</pre>
This example demonstrates the use of a nested classpath element as well
as some of the other optional attributes.
<pre>
&lt;ejbjar srcdir="${build.classesdir}"
descriptordir="${src}"&gt;
&lt;iplanet destdir="${assemble.ejbjar}"
iashome="${ias.home}"
debug="yes"
keepgenerated="yes"&gt;
&lt;classpath&gt;
&lt;pathelement path="."/&gt;
&lt;pathelement path="${build.classpath}"/&gt;
&lt;/classpath&gt;
&lt;/iplanet&gt;
&lt;include name="**/*-ejb-jar.xml"/&gt;
&lt;exclude name="**/*ias-*.xml"/&gt;
&lt;/ejbjar&gt;</pre>
This example demonstrates the use of basejarname attribute. In this
case, the completed EJB-JAR will be named "HelloWorld.jar" If multiple
EJB descriptors might be found, care must be taken to ensure that the completed
JAR files don't overwrite each other.
<pre>
&lt;ejbjar srcdir="${build.classesdir}"
descriptordir="${src}"
basejarname="HelloWorld"&gt;
&lt;iplanet destdir="${assemble.ejbjar}"
classpath="${ias.ejbc.cpath}"/&gt;
&lt;include name="**/*-ejb-jar.xml"/&gt;
&lt;exclude name="**/*ias-*.xml"/&gt;
&lt;/ejbjar&gt;</pre>
This example demonstrates the use of the dtd nested element. If the local
copies of the DTDs are included in the classpath, they will be automatically
referenced without the nested elements. In iAS 6.0 SP2, these local DTDs are
found in the [iAS-install-directory]/APPS directory. In iAS 6.0 SP3, these
local DTDs are found in the [iAS-install-directory]/dtd directory.
<pre>
&lt;ejbjar srcdir="${build.classesdir}"
descriptordir="${src}"&gt;
&lt;iplanet destdir="${assemble.ejbjar}"&gt;
classpath="${ias.ejbc.cpath}"/&gt;
&lt;include name="**/*-ejb-jar.xml"/&gt;
&lt;exclude name="**/*ias-*.xml"/&gt;
&lt;dtd publicId="-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN"
location="${ias.home}/APPS/ejb-jar_1_1.dtd"/&gt;
&lt;dtd publicId="-//Sun Microsystems, Inc.//DTD iAS Enterprise JavaBeans 1.0//EN"
location="${ias.home}/APPS/IASEjb_jar_1_0.dtd"/&gt;
&lt;/ejbjar&gt;</pre>
<h3><a name="ejbjar_jonas">JOnAS (Java Open Application Server) element</a></h3>
<p>The <code>&lt;jonas&gt;</code> nested element is used to build JOnAS-specific stubs and
skeletons thanks to the <code>GenIC</code> specific tool, and construct a JAR
file which may be deployed to the JOnAS Application Server. The build process
will always determine if the EJB stubs/skeletons and the EJB-JAR file are up to
date, and it will do the minimum amount of work required.</p>
<p>Like the WebLogic element, a naming convention for the EJB descriptors is
most commonly used to specify the name for the completed JAR file. For example,
if the EJB descriptor <code>ejb/Account-ejb-jar.xml</code> is found in the
descriptor directory, the <code>&lt;jonas&gt;</code> element will search for a JOnAS-specific
EJB descriptor file named <code>ejb/Account-jonas-ejb-jar.xml</code> and a JAR
file named <code>ejb/Account.jar</code> will be written in the destination
directory. But the <code>&lt;jonas&gt;</code> element can also use the JOnAS naming
convention. With the same example as below, the EJB descriptor can also be named
<code>ejb/Account.xml</code> (no base name terminator here) in the descriptor
directory. Then the <code>&lt;jonas&gt;</code> element will search for a JOnAS-specific EJB
descriptor file called <code>ejb/jonas-Account.xml</code>. This convention do
not follow strictly the ejb-jar naming convention recommendation but is
supported for backward compatibility with previous version of JOnAS.</p>
<p>Note that when the EJB descriptors are added to the JAR file, they are
automatically renamed <code>META-INF/ejb-jar.xml</code> and
<code>META-INF/jonas-ejb-jar.xml</code>.</p>
<p>Of course, this naming behavior can be modified by specifying attributes in
the ejbjar task (for example, basejarname, basenameterminator, and flatdestdir)
as well as the iplanet element (for example, suffix). Refer to the appropriate
documentation for more details.</p>

<h3>Examples</h3>

JOnAS EJB container. This example requires the naming standard to be used for
the deployment descriptors. Using this format will create a EJB JAR file for
each variation of &nbsp;'*-jar.xml' that is found in the deployment descriptor
directory.&nbsp;</p>
<pre>
&lt;ejbjar srcdir="${build.classes}"
