RESOURCE_LOCAL transaction-type can be only used in Application-managed Entity Manager? In this question, the Statefull Session Bean should use Application-managed Entity Manager?

[admin]

I am not sure I understand your question. In this question, em could be injected also. It doesn't have to be RESOURCE_LOCAL.

em.getTransaction() will throw IllegalStateException if invoked on a JTA entity manager.

Code: Select all

1. EntityTransaction et = em.getTransaction();
2. et.setRollbackOnly(); 

Could you please describe case(s) in which et instance would be non-active transaction on line 2?

[admin]

What if processAccount is the first method to be invoked. In the given code, there is no call to begin. Thus the transaction is not active at this point and therefore a call to setRollBackOnly will throw IllegalStateException.

HTH,
Paul.

I see now, transaction is not active because begin has not been called, thank you.
