I'm prepearing to take 310-090 exam next week and have unresolved questions. I read ejb
2.0 spec and still can�t find answer on my question. Any answers will be so much appreciated.
Here it is: Which three, of a session bean that implements SessionSynchronization, are called with an
unspecified transaction context? (Choose three.)
Answer: A, C, E
That means that if the session bean was called with unspecified context (but not without it) then I won�t be able to rollback the transaction in beforeCompletion method. I tried to find any references in ejb spec about circumstances when do SessionSynchronization callback methods won�t be called but I couldn�t find anything.
Can anyone explain it for me why does B and D are not correct.
