EJB transactions Transaction Attributes for Bean-Managed Transactions must not be used in Entity beans as the bean specifies transaction demarcations using methods in the javax.transaction.UserTransaction interface. These transactions include stateful or stateless session beans with a transaction-type set to Bean. Any stateful or stateless session is managed by other methods that is why Entity beans cannot use bean-managed transactions. For stateless session beans, it need to be considered that the entering and exiting transaction contexts must match. In case of stateful session beans, the entering and exiting transaction contexts may or may not match. In case it is not matched then EJB container server maintains associations between the bean and non-terminated transaction. Rohit Sharma 08-21-2014 06:48 PM
