Hi Experts, Im using injected persistent context in my session bean. @PersistentContext(unit="AppConext") private EntityManeger entityManager; In this session bean i've a method in which,i iterate over the list. Lets say this method as method1(); The scenario is somthing like this.. @TransactionAttribute(REQUIRES_NEW) public voic method1() { ......some code..... for(SomeObject obj : someObjectList) { ..............some code.... //call method2 method2(obj); .........some code...... } } @TransactionAttribute(REQUIRES_NEW) public void method2() { } What is happening here is when i call mehod2 and pass value to it from list, the method throws NoEntityFound excexption and ejb transaction rolls back. In the catch block of method2 , i'm catching NoEntityFoundException and getting the programm flow to normal flow. Throwing of NoEntiyFound exception is an expected behaviour. But my requirement is that i need to continue the iteration over the other values in the list. But when the programm comes back to method1 and the moment it does some procesing i get exception like: javax.transaction.RollbackException: Already marked for rollback, tx=TransactionImpl:XidImpl[FormatId=257, GenericJDBCException..cannot open connection..session close.... 1)What is the technical reson behind exception in method1? 2)What should i do to solve it so that my code processes the rest of the elements in the list? Thanking in advance for any help. Thanks Vedgunjan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4033496#...
