You should be able to run this operation within the scope of a transaction and have both operations work as a single unit You can do this programmatically kind of like this for a hint: | UserTransaction tx = NamingContext.lookup("javax.transaction.UserTransaction"); | tx.begin(); | | //your code here | addMyUser | userModule.addUser | | tx.commit(); | Even more elegant is using container-managed transaction using EJB 3.0 or something like that. I have personally used it with EJB 3.0 container managed transactions and it works just fine.
