I have a transaction which spans 2 session beans and each of these session beans interact with a different EntityManager. Also, these EntityManagers interact with different data sources.
The problem is, when I try to call o method on the second EntityManager, I get this "Could not enlist in transaction on entering meta-aware object!" exception.
I've read somewhere that if I invoke another sessionbean from a session bean (which is my case), I should use the same PersistenceContext in both EJBs. But I can't do this, since my PersistenceContexts point to different data sources.
