One small question: I am using EJB 3.0, seam 1.2.1 and Jboss 4.0.5.
I have changed from Jboss transaction managment to seam to Seam-managed transactions, now can standard ejb3.0 annotations regarding transaction demarcation like @TransactionAttribute(TransactionAttributeType.REQUIRED) on Stateful Session Beans still be used or do I have to change to seam annotations like @Transactional(TransactionPropagationType.REQUIRED)
They can still be used, yes.
