Explanation

A CMP (Container-Managed Persistence) entity bean on WebLogic requires one J2EE standard deployment descriptor (ejb-jar.xml) and TWO WebLogic-specific descriptors (weblogic-ejb-jar.xml and weblogic-cmp-jar.xml). The weblogic-cmp-jar.xml specifically defines CMP mapping and is required in addition to the standard descriptors.
