/**
 * WebSphere deployment tool that augments the ejbjar task.
 * 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.
