Integration

I think this belongs here rather than the AQ forum. Apologies if not.

I get an exception when deploying an ear file consisting of 1 stateless session bean and 1 MDB. The MDB is reading a JMS queue implemented by Oracle AQ.
The deployment is reported as successful through the Enterprise Manager browser interface but a glance in the app log file reveals:

Any pointers as to what this might be? I can supply the descriptors/config files as required.

I'm a newbie to Oracle AS & AQ; I'm hoping this is something simple. Many thanks.
