Hi,

when a method of my EJB is invoked I get the information to which database to 
connect by passing the datasource name (not the name exactly). Therefore I 
cannot define all datasources in persistence.xml fixed. I instantiate the 
EntityManagerFactory and EntityManager by myself and this I think hinders the 
usage of JTA, CMT with JBoss. The transaction cannot be joined by hibernate. Is 
there a concept existing to handle this "datasource by EJB invokation" approach?
It runs if I do it without JTA, CMT and with RESOURCE_LOCAL and BMT. Maybe I 
can tell JBoss which EntityManagerFactory to use?

Cheers
Oliver
