My service EJB which uses hibernate/JPA2 does not work if it is injected in a ServletFilter. I cannot determine exactly if this is a hibernate or a jboss problem.

I get the following warning at jboss startup:

I am not sure if this has something to do with the error which occurs if I accessing the EJB:
