i noticed using extended entity manager (@persistencecontext(type=persistencecontexttype.extended) stateless session bean @stateless, when specify injected entitymanager extended persistence context, should use @stateful session bean, because extended entitymanagers still live beyond scope of jta transaction, have 2 solutions:
- change stateless stateful session bean: in case please note extended entity managers create persistence context when stateful session bean instance created lasts until bean removed.
- change extended entity manager transaction-scoped entity manager using
type=persistencecontexttype.transaction: persistence context of transaction-scoped entity manager begins when transaction begins , lasts until end of transaction, persistence context of extended entity manager last entire length of conversation.
