<h2><a name="introduction">Introduction</a></h2>
<p>Ant provides a number of optional tasks for developing 
<a href="http://java.sun.com/products/ejb">Enterprise Java Beans (EJBs)</a>. 
In general these tasks are specific to the particular vendor's EJB Server. At present the tasks support
<a href="http://www.bea.com">Weblogic</a> 4.5.1 and 5.1 EJB servers. Over time we expect further optional tasks 
to support additional EJB Servers.

<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 serialised 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>
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 serialised 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>
Each descriptor is examined to determiune whether the generated classes are out of date and need to be 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 serialised 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or are out of date, the ejbc tool is run to generate new versions.
