i try to process a long running transaction on database.
The EntityManager ist injected as follows:
@PersistenceContext(type=PersistenceContextType.EXTENDED) private EntityManager em;
But when the application deploys, i got the following message:
java.lang.RuntimeException: It is illegal to inject an EXTENDED PC into something other than a SFSB
Can anyone tell me what SFSB means?
