Startup of full test environment on WebSphere Commerce Developer fails to load a JAR file Technote
(troubleshooting)Problem(Abstract) When you start the full test environment on the WebSphere Commerce Developer, a JAR file fails to load and returns the following null pointer exception:
[04/01/06 16:04:46:391 GMT] 4c952d66 EJBContainerI I WSVR0037I: Starting EJB jar: WebSphereCommerceServerExtensionsData.jar

Cause Generalizations within the WebSphereCommerceServerExtensionsData.jar file do not exist. Within the WebSphereCommerceServerExtensionsData.jar file, the ibm-ejb-ext-jar.xml file contains some generalizations. Ensure that these generalizations exist in the referenced file.
For example, the following lines are contained within the ibm-ejb-ext-jar.xml file:
<generalizations xmi:id="EjbGeneralization_1082977161640">
<subtype xmi:type="ejb:Session"
href="META-INF/ejb-jar.xml#CategoryHelper"/>
<supertype xmi:type="ejb:Session"
href="META-INF/ejb-jar.xml#ExtensionJDBCHelper"/>
</generalizations>
<generalizations xmi:id="EjbGeneralization_1121430169046">
<subtype xmi:type="ejb:Session"
href="META-INF/ejb-jar.xml#Session_1131382089968"/>
<supertype xmi:type="ejb:Session"
href="META-INF/ejb-jar.xml#ExtensionJDBCHelper"/>
</generalizations>
The href values point to the META-INF/ejb-jar.xml file. This file is also in the JAR file. Within the ejb-jar.xml file, CategoryHelper and ExtensionJDBCHelper both exist while entry Session_1131382089968 does not. Because there is no entry for Session_1131382089968, a null value is returned.Resolving the problem To resolve this null pointer error, remove the references to the missing bean. In this particular example, the following lines should be removed:
<generalizations xmi:id="EjbGeneralization_1121430169046">
<subtype xmi:type="ejb:Session"
href="META-INF/ejb-jar.xml#Session_1131382089968"/>
<supertype xmi:type="ejb:Session"
href="META-INF/ejb-jar.xml#ExtensionJDBCHelper"/>
</generalizations>
