Here is the error:
Caused by: javax.servlet.ServletException: com.xxxxx.user.mgt.session.UserManagementBusinessD elegate: method batchCreateUserRequestActivities(Ljav
a/util/ArrayListV not found

This is a method within a session bean in an EJB called from the portlet. This works fine in Unit testing and on our DEV box. I have verified that the correct EAR is installed on the PROD box,and the Client EJB jar is correct, but it seems to ignore it. Other methods within the session bean work fine.

Any suggestions are appreciated.
