After moving CLM applications to new servers, QM reports NullPointerException via equinoxbridgeservlet

We moved our 4 CLM applications from SLES-10 servers to SLES-11 servers.  The applications are deployed using Websphere Application Server.  We have the JTS and CCM on one server.  RM an QM are on a second server.  The SQL Server databases remain on their original database server.  After the move, the JTS, CCM, and RM applications all work just fine.  However, the QM application does not.  The WAS logs contain the following error:

com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0068E: Uncaught exception created in one of the service methods of the servlet equinoxbridgeservlet in application QM. Exception created : java.lang.NullPointerException

Does anyone have any ideas?  Please note that I am just the CLM tools admin.  I am not a Websphere Admin or Linux server admin.  I have to rely on the services of other groups that provide this expertise.
