We have a CMP 2.0 EJB Entity bean,
with a session.
We can create the Session bean,
execute the findAll,
and iterate all beans.
However, once we call a getter on the remote or local interface of the entity bean, we get an EJB exception:
"javax.ejb.EJBException: Unknown load group: name=group name"
We get this on SQLserver, DB2 and Oracle, so it is probably not a JDBC driver problem.
Our stuff runs on the IBM WebSphere WAS 5, but it is stuck here on the JBOSS.
I had exactly the same problem. Fixed by commenting
section from my jbosscmp-jdbc.
