Support is currently provided for 'vanilla' EJB1.1 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 EJB1.1 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 <support> 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The jar files are only built if they are out of date. Each deployment tool element will examine its target jar file and determine if it is out of date with respect to the class files and deployment descriptors that make up the bean.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 "naming" 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 <ejb-name> 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 <ejb-name> were to be given in the deployment descriptor as follows: <pre> <ejb-jar> <enterprise-beans> <entity> <ejb-name>Sample</ejb-name> <home>org.apache.ant.ejbsample.SampleHome</home> </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 <ejbjar> 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 "basejarname" 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>Parameters:</h3> <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">descriptordir</td> <td valign="top">The base directory under which to scan for EJB deployment descriptors.

In all other respects the behaviour is the same as the classpath attribute.</p> <a name="ejbjar-dtd"><h4>dtd</h4></a> <p>The <dtd> 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 <dtd> 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 <dtd> 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.

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.

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 <type-storage> 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 <type-storage> element. In the above example, you would define this as META-INF/Customer-weblogic-cmp-rdbms-jar.xml.</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">destdir</td> <td valign="top">The base directory into which the generated weblogic ready jar files are deposited.

For example, if the descriptor named "Account-ejb-jar.xml" is processed, the EJB-JAR will be named "Account.jar" <pre> <ejbjar srcdir="${build.classesdir}" descriptordir="${src}"> <iplanet destdir="${assemble.ejbjar}" classpath="${ias.ejbc.cpath}"/> <include name="**/*-ejb-jar.xml"/> <exclude name="**/*ias-*.xml"/> </ejbjar></pre> This example demonstrates the use of a nested classpath element as well as some of the other optional attributes. <pre> <ejbjar srcdir="${build.classesdir}" descriptordir="${src}"> <iplanet destdir="${assemble.ejbjar}" iashome="${ias.home}" debug="yes" keepgenerated="yes"> <classpath> <pathelement path="."/> <pathelement path="${build.classpath}"/> </classpath> </iplanet> <include name="**/*-ejb-jar.xml"/> <exclude name="**/*ias-*.xml"/> </ejbjar></pre> This example demonstrates the use of basejarname attribute. In this case, the completed EJB-JAR will be named "HelloWorld.jar" If multiple EJB descriptors might be found, care must be taken to ensure that the completed JAR files don't overwrite each other. <pre> <ejbjar srcdir="${build.classesdir}" descriptordir="${src}" basejarname="HelloWorld"> <iplanet destdir="${assemble.ejbjar}" classpath="${ias.ejbc.cpath}"/> <include name="**/*-ejb-jar.xml"/> <exclude name="**/*ias-*.xml"/> </ejbjar></pre> This example demonstrates the use of the dtd nested element.

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 <jonas> 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 <jonas> 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 <jonas> 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> Parameters:</h3> <table border="1" cellspacing="0" cellpadding="2"> <tbody> <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">destdir</td> <td valign="Top">The base directory into which the generated JAR files will be written.

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 '*-jar.xml' that is found in the deployment descriptor directory. </p> <pre> <ejbjar srcdir="${build.classes}" descriptordir="${descriptor.dir}"> <jonas destdir="${deploymentjars.dir}" jonasroot="${jonas.root}" orb="RMI"/> <include name="**/*.xml"/> <exclude name="**/jonas-*.xml"/> <support dir="${build.classes}"> <include name="**/*.class"/> </support> </ejbjar> </pre> <p>This example shows ejbjar being used to generate a single deployment jar using a JOnAS EJB container. This example does require the deployment descriptors to use the naming standard.
