| * 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> |

| * 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. |
