I'm experiencing a problem while using Hibernate with MessageDrivenBeans on WebLogic Server. When I deploy my application the server casts



I was trying to search for a solution, but couldn't find any. Some are saying it's a missing 3rd party library that Hibernate needs, other -- that's a compatibility problem, i.e. class loader isolation not working properly on WebLogic and Hibernate library isn't seen.

Have you seen something similar? Any ideas are very appreciated. Thanks in advance.
