<h2 id="introduction">Introduction</h2>
<p>Ant provides a number of optional tasks for developing 1.x and
2.x <a href="https://www.oracle.com/technetwork/java/index-jsp-140203.html" 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:</p>

<ul>
  <li><a href="https://www.borland.com" target="_top">Borland</a>Application Server 4.5</li>
  <li><a href="https://web.archive.org/web/20020202082841/http://www.iplanet.com/products/iplanet_application/home_ias.html"
         target="_top">iPlanet</a> Application Server 6.0</li>
  <li><a href="https://www.jboss.org/" target="_top">JBoss 2.1</a> and above EJB servers</li>
  <li><a href="https://web.archive.org/web/20080516210506/http://www.ironflare.com/"
         target="_top">Orion Application Server</a> 2.0 (<em>since Ant 1.10.2</em>)</li>
  <li><a href="https://www.oracle.com/corporate/acquisitions/bea/" target="_top">WebLogic</a> 4.5.1 through to 7.0 EJB servers</li>
  <li><a href="https://jonas.ow2.org/" target="_top">JOnAS</a> 2.4.x and 2.5 Open Source EJB server</li>
  <li><a href="https://www.ibm.com/websphere" target="_top">IBM WebSphere</a> 4.0</li>
</ul>
<p>Vendors such as BEA and IBM now provide custom Ant tasks to work with their particular
products. More importantly, EJB 3.0 renders this whole process obsolete.  Accordingly, development
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 EJB 2.x
applications and definitely not new EJB 2.x servers.</p>

<h2 id="ddcreator">ddcreator</h2>
<h3>Description</h3>
<p><code>ddcreator</code> 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 <code>include</code> and <code>exclude</code> selection
mechanisms.</p>

<h3>Parameters</h3>
<table class="attr">
  <tr>
    <th scope="col">Attribute</th>
    <th scope="col">Description</th>
    <th scope="col">Required</th>
  </tr>
  <tr>
    <td>descriptors</td>
    <td>This is the base directory from which descriptors are selected.</td>
    <td>Yes</td>
  </tr>
  <tr>
    <td>dest</td>
    <td>The directory where the serialized deployment descriptors will be written</td>
    <td>Yes</td>
  </tr>
  <tr>
    <td>classpath</td>
    <td>This is the classpath to use to run the underlying WebLogic <code>ddcreator</code> tool.
      This must include the <code>weblogic.ejb.utils.DDCreator</code> class</td>
    <td>No</td>
  </tr>
</table>
<h3>Examples</h3>
<pre>
&lt;ddcreator descriptors=&quot;${dd.dir}&quot;
           dest=&quot;${gen.classes}&quot;

&lt;/ddcreator&gt;</pre>

<hr/>
<h2 id="ejbc">ejbc</h2>
<h3>Description</h3>
<p>The <code>ejbc</code> task will run WebLogic's <kbd>ejbc</kbd> 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 <kbd>ejbc</kbd> tool is run to generate new versions.</p>

<h2 id="iplanet-ejbc">iplanet-ejbc</h2>

<h3>Description</h3>
<p>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>
<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 <kbd>ejbc</kbd>
utility be called to generate new stubs and skeletons.</p>

<h3>Parameters specified as nested elements</h3>

<p>The <code>wlrun</code> task supports nested <code>&lt;classpath&gt;</code>
and <code>&lt;wlclasspath&gt;</code> elements to set the respective classpaths.</p>

<h3>Examples</h3>

<p>This example shows the use of <code>wlrun</code> to run a server under WebLogic 5.1</p>

<pre>
    &lt;wlrun taskname=&quot;myserver&quot;
           classpath=&quot;${weblogic.boot.classpath}&quot;
           wlclasspath=&quot;${weblogic.classes}:${code.jars}&quot;
           name=&quot;myserver&quot;
           home=&quot;${weblogic.home}&quot;
           properties=&quot;myserver/myserver.properties&quot;/&gt;
</pre>

<p>This example shows <code>wlrun</code> being used to run the <samp>petstore</samp> server under
WebLogic 6.0</p>

<pre>
&lt;wlrun taskname=&quot;petstore&quot;
       classpath=&quot;${weblogic.classes}&quot;
       name=&quot;petstoreServer&quot;
       domain=&quot;petstore&quot;
       home=&quot;${weblogic.home}&quot;

       beahome=&quot;${bea.home}&quot;/&gt;</pre>

<hr/>
<h2 id="wlstop">wlstop</h2>
<h3>Description</h3>

<p>The <code>wlstop</code> task is used to stop a WebLogic instance which is currently running. To
shut down an instance you must supply both a username and a password. These will be stored in the
clear in the build script used to stop the instance. For security reasons, this task is therefore
only appropriate in a development environment.</p>

<p>This task works for most versions of WebLogic, including 6.0. You need to specify
the <var>BEAHome</var> to have this task work correctly under 6.0</p>

    <td>The delay in seconds after which the server will stop.</td>
    <td>No; default is <q>0</q> (immediate shutdown)</td>
  </tr>
</table>

<h3>Parameters specified as nested elements</h3>

<p>The classpath of the <code>wlstop</code> task can be set by a <code>&lt;classpath&gt;</code>
nested element.</p>

<h3>Examples</h3>

<p>This example show the shutdown for a WebLogic 6.0 server</p>

<pre>
&lt;wlstop classpath=&quot;${weblogic.classes}&quot;
        user=&quot;system&quot;
        url=&quot;t3://localhost:7001&quot;
        password=&quot;foobar&quot;
        beahome=&quot;${bea.home}&quot;/&gt;</pre>

<hr/>
<h2 id="ejbjar">ejbjar</h2>
<h3>Description</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&mdash;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 <code>weblogic.ejbc</code> tool</li>
  <li>IBM WebSphere 4.0</li>
  <li>TOPLink for WebLogic 2.5.1-enabled entity beans</li>
  <li><a href="https://jonas.ow2.org/" target="_top">JOnAS</a> 2.4.x and 2.5 Open Source EJB
    server</li>
  <li>IronFlare Orion Application Server 2.0</li>
</ul>

<p>The task works as a directory scanning task, and performs an action for each deployment
descriptor found. As such the <code>includes</code> and <code>excludes</code> should be set to
ensure that all desired EJB descriptors are found, but no application server descriptors are
found. For each descriptor found, <code>ejbjar</code> 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, <code>ejbjar</code> 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="https://commons.apache.org/bcel/"
target="_top">BCEL</a> <a href="../install.html#librarydependencies">library</a> 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 id="naming">Naming convention</h3>

<code>Ejbjar</code> 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 <var>naming</var> attribute. It supports the following values
<dl>
<dt><q>descriptor</q></dt>
<dd><p>This is the default naming scheme. The name of the generated bean is derived from the name of
the deployment descriptor.  For an <samp>Account</samp> bean, for example, the deployment descriptor
would be named <samp>Account-ejb-jar.xml</samp>. Vendor specific descriptors are located using the
same naming convention. The WebLogic bean, for example, would be
named <samp>Account-weblogic-ejb-jar.xml</samp>. 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.</p></dd>

<dt><q>ejb-name</q></dt>
<dd><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 <samp>ejb-jar.xml</samp> 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:</p>
<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>
<p>then the name of the generated bean would be <samp>Sample.jar</samp></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></dd>
<dt><q>directory</q></dt>
<dd><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 <samp>/home/user/dev/appserver/dd/sample</samp>, then the generated bean will be
named <samp>sample.jar</samp></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></dd>

<dt><q>basejarname</q></dt>
<dd><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 <var>basejarname</var> 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></dd>
</dl>

<h3 id="ejbjar_deps">Dependencies</h3>
<p>In addition to the bean classes, <code>ejbjar</code> is able to ad additional classes to the
generated EJB jar. 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, <code>ejbjar</code> 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><em>Since Ant 1.5</em> the task uses the <a href="https://commons.apache.org/bcel/"
target="_top">BCEL</a> library to analyze the bean's class files directly, rather than loading them
into the JVM. This also allows <code>ejbjar</code> to add all of the required support classes for a
bean and not just super classes.</p>

<p><em>Since Ant 1.5</em>, a <var>dependency</var> attribute allows the buildfile to control what
additional classes are added to the generated jar. It takes three possible values</p>
<ul>
  <li><q>none</q>&mdash;only the bean classes and interfaces described in the bean's descriptor are
    added to the jar.</li>
  <li><q>super</q>&mdash;this is the default value and replicates the original <code>ejbjar</code>
    behaviour where super classes and super interfaces are added to the jar</li>
  <li><q>full</q>&mdash;In this mode all classes used by the bean's classes and interfaces are added
    to the jar</li>
</ul>
<p>The <q>super</q> and <q>full</q> values require the <a href="https://commons.apache.org/bcel/"
target="_top">BCEL</a> library to be available. If it is not, <code>ejbjar</code> will drop back to
the behaviour corresponding to the value <q>none</q>.</p>

<h3>Parameters specified as nested elements</h3>

<p>In addition to the vendor specific nested elements, the <code>ejbjar</code> 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>

<h4 id="ejbjar-dtd">dtd</h4>

<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 <code>ejbjar</code> 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 class="attr">
  <tr>
    <th scope="col">Attribute</th>
    <th scope="col">Description</th>
    <th scope="col">Required</th>
  </tr>
  <tr>
    <td>publicId</td>
    <td>The public Id of the DTD for which the location is being provided</td>
    <td>Yes</td>
  </tr>
  <tr>
    <td>location</td>
    <td>The location of the local copy of the DTD. This can either be a file or a resource loadable
      from the classpath.</td>
    <td>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="../Types/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 <code>ejbjar</code> generates more than one jar file, the support files are
added to each one.</p>

<h3>Vendor-specific deployment elements</h3>

<p>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.</p>

<h3 id="ejbjar_jboss">Jboss element</h3>

<p>The <code>jboss</code> element searches for the JBoss specific deployment descriptors and adds
them to the final EJB jar file. JBoss has two deployment descriptors:</p>
<ul>
  <li><samp>jboss.xml</samp></li>
  <li>for container manager persistence:
    <table>
      <tr><th scope="col">CMP version</th><th scope="col">File name</th></tr>
      <tr><td>CMP 1.0</td><td><samp>jaws.xml</samp></td></tr>
      <tr><td>CMP 2.0</td><td><samp>jbosscmp-jdbc.xml</samp></td></tr>
    </table>
  </li>
</ul>
<p>The JBoss server uses hot deployment and does not require compilation of additional stubs and
skeletons.</p>

    <th scope="col">Description</th>
    <th scope="col">Required</th>

  </tr>
  <tr>
    <td>genericjarsuffix</td>
    <td>A generic jar is generated as an intermediate step in build the JBoss deployment jar. The
      suffix used to generate the generic jar file is not particularly important unless it is
      desired to keep the generic jar file. It should not, however, be the same as the suffix
      setting.</td>
    <td>No; defaults to <q class="no-break">-generic.jar</q></td>
  </tr>
  <tr>
    <td>suffix</td>
    <td>String value appended to the basename of the deployment descriptor to create the filename of
      the JBoss EJB jar file.</td>

  <tr>

    <td>This controls whether the generic file used as input to <kbd>ejbc</kbd> is retained.</td>
    <td>No; defaults to <q>false</q></td>
  </tr>
</table>

<h3 id="ejbjar_weblogic">WebLogic element</h3>

<p>The <code>weblogic</code> element is used to control the <code>weblogic.ejbc</code> compiler for
generating WebLogic EJB jars. Prior to Ant 1.3, the method of locating CMP descriptors was to use
the <code>ejbjar</code> naming convention. So if your EJB jar was
called, <samp>Customer-ejb-jar.xml</samp>, your WebLogic descriptor was
called <samp>Customer-weblogic-ejb-jar.xml</samp> and your CMP descriptor had to
be <samp>Customer-weblogic-cmp-rdbms-jar.xml</samp>. In addition,
the <code>&lt;type-storage&gt;</code> element in the WebLogic descriptor had to be set to the
standard name <samp>META-INF/weblogic-cmp-rdbms-jar.xml</samp>, 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, <code>ejbjar</code> parses the WebLogic deployment descriptor to discover the CMP
descriptors, which are then included automatically. This behaviour is controlled by
the <var>newCMP</var> 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 <samp>META-INF/Customer-weblogic-cmp-rdbms-jar.xml</samp>.</p>

<p>The <code>weblogic</code> 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 classpaths 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.</p>

<h3>TOPLink for WebLogic element</h3>

<p><em><u>Deprecated</u></em></p>

<p>The <code>toplink</code> element is no longer required. Toplink beans can now be built with the
standard <code>weblogic</code> element, as long as the <var>newCMP</var> attribute is set
to <q>true</q></p>

<p>The <code>TopLink</code> element is used to handle beans which use Toplink for the CMP
operations. It is derived from the standard <code>weblogic</code> element so it supports the same
set of attributes plus these additional attributes</p>

<h3>Examples</h3>

EJB container. This example requires the naming standard to be used for the deployment

<p>This final example shows how you would set-up <code>ejbjar</code> under WebLogic 6.0. It also
shows the use of the <code>&lt;support&gt;</code> element to add support files</p>

<pre>

   &lt;include name=&quot;**/*-ejb-jar.xml&quot;/&gt;

        &lt;include name=&quot;**/*.class&quot;/&gt;
   &lt;/support&gt;

             keepgeneric=&quot;true&quot;
             suffix=&quot;.jar&quot;
             rebuild=&quot;false&quot;&gt;
     &lt;classpath&gt;
        &lt;pathelement path=&quot;${build.classes.server}&quot;/&gt;
     &lt;/classpath&gt;
     &lt;wlclasspath&gt;
        &lt;pathelement path=&quot;${weblogic.classes}&quot;/&gt;
     &lt;/wlclasspath&gt;
   &lt;/weblogic&gt;
&lt;/ejbjar&gt;</pre>

<h3 id="ejbjar_websphere">WebSphere element</h3>

<p>The <code>websphere</code> 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:</p>
<ul>
  <li><samp>ibm-ejb-jar-bnd.xmi</samp></li>
  <li><samp>ibm-ejb-jar-ext.xmi</samp></li>
</ul>
<p>and another two for container managed entity beans:</p>
<ul>
  <li><samp>Map.mapxmi</samp></li>
  <li><samp>Schema.dbxmi</samp></li>
</ul>
<p>In terms of WebSphere, the generation of container code and stubs is called <em>deployment</em>.
This step can be performed by the <code>websphere</code> element as part of the jar generation
process. If the switch <var>ejbdeploy</var> is on, the <kbd>ejbdeploy</kbd> tool from the
WebSphere toolset is called for every EJB jar. Unfortunately, this step only works, if you use the
IBM JDK. Otherwise, the <kbd>rmic</kbd> (called by <kbd>ejbdeploy</kbd>) throws
a <code>ClassFormatError</code>. Be sure to switch <var>ejbdeploy</var> off, if Ant runs with Oracle
JDK or OpenJDK.</p>

<p>For the <code>websphere</code> element to work, you have to provide a complete classpath, that
contains all classes, that are required to reflect the bean classes. For <kbd>ejbdeploy</kbd> to
work, you must also provide the classpath of the <kbd>ejbdeploy</kbd> tool and set
the <code>websphere.home</code> property (look at the examples below).</p>

<h3 id="ejbjar_iplanet">iPlanet Application Server (iAS) element</h3>

<p>The <code>&lt;iplanet&gt;</code> 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>
<p>Like the <code>weblogic</code> 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 <samp>ejb/Account-ejb-jar.xml</samp> is found in the descriptor directory,
the <code>iplanet</code> element will search for an iAS-specific EJB descriptor file
named <samp>ejb/Account-ias-ejb-jar.xml</samp> (if it isn't found, the task will fail) and a JAR
file named <samp>ejb/Account.jar</samp> will be written in the destination directory.  Note that
when the EJB descriptors are added to the JAR file, they are automatically
renamed <samp>META-INF/ejb-jar.xml</samp> and <samp>META-INF/ias-ejb-jar.xml</samp>.</p>
<p>Of course, this naming behaviour can be modified by specifying attributes in
the <code>ejbjar</code> task (for example, <var>basejarname</var>, <var>basenameterminator</var>,
and <var>flatdestdir</var>) as well as the <code>iplanet</code> element (for
example, <var>suffix</var>).  Refer to the appropriate documentation for more details.</p>

<p>As noted above, the <code>iplanet</code> element supports
additional <code>&lt;classpath&gt;</code> nested elements.</p>
<h3>Examples</h3>
<p>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 <samp>Account-ejb-jar.xml</samp> is processed, the EJB-JAR will be
named <samp>Account.jar</samp></p>
<pre>
&lt;ejbjar srcdir="${build.classesdir}"
        descriptordir="${src}"&gt;

    &lt;iplanet destdir="${assemble.ejbjar}"

    &lt;include name="**/*-ejb-jar.xml"/&gt;
    &lt;exclude name="**/*ias-*.xml"/&gt;
&lt;/ejbjar&gt;</pre>

<p>This example demonstrates the use of a nested <code>classpath</code> element as well as some of
the other optional attributes.</p>
<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>

<p>This example demonstrates the use of <var>basejarname</var> attribute.  In this case, the
completed EJB jar will be named <samp>HelloWorld.jar</samp>.  If multiple EJB descriptors might be
found, care must be taken to ensure that the completed JAR files don't overwrite each other.</p>

<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>

<p>This example demonstrates the use of the <code>dtd</code> 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 <samp>[iAS-install-directory]/APPS</samp> directory.  In iAS 6.0 SP3, these local DTDs are found
in the <samp>[iAS-install-directory]/dtd</samp> directory.</p>

<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 id="ejbjar_jonas">JOnAS (Java Open Application Server) element</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 <samp>ejb/Account-ejb-jar.xml</samp> is found in the descriptor directory,
the <code>&lt;jonas&gt;</code> element will search for a JOnAS-specific EJB descriptor file
named <samp>ejb/Account-jonas-ejb-jar.xml</samp> and a JAR file named <samp>ejb/Account.jar</samp>
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 <samp>ejb/Account.xml</samp> (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 <samp>ejb/jonas-Account.xml</samp>. 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 <samp>META-INF/ejb-jar.xml</samp> and <samp>META-INF/jonas-ejb-jar.xml</samp>.</p>

<p>Of course, this naming behavior can be modified by specifying attributes in
the <code>ejbjar</code> task (for example, <var>basejarname</var>, <var>basenameterminator</var>,
and <var>flatdestdir</var>) as well as the <code>iplanet</code> element (for
example, <var>suffix</var>). Refer to the appropriate documentation for more details.</p>

<p>This task creates a directory for scratch data inside of
  the <a href="../running.html#tmpdir">temporary directory</a>.</p>
