In some specific cases, I would like to control the transaction boundary. For example, I tried


@Stateless
publis class MyLogicBean implements MyLogic {

public void f1WithTx() {...}
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public void f2NoTx() {...}
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public void f3WithTx() {...}

}


When in another session bean that I called


f1WithTx();
f2NoTx() ;
f3WithTx();


unfortunately, the f3WithTx() did throw exception, complaining about no session or session is closed.

Is this the right way to control transaction boundary? What is the best practice?


Thanks in advance.
