To my knowledge, m.flush() guarantees that the database commit happens before the method returns (or else it will throw an exception). I can't understand why you inject an EntityManagerFactory instead of an EntityManager. What is the purpose of afterCompletion()? And why is the bean stateful and not stateless? I don't see any state variables that would warrant a stateful bean. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4002777#...
