I was forwarded these 2 questions and would like your guys expert opinion on the correct answer (He is referring to an app that is running as an MQClient):

1.Is it possible to use transacted JMS Sessions - within a Message Driven Bean or otherwise - if I'm using the Client model ?

2.Let's say I am using non-transacted JMS Sessions in an application that has created multiple sessions and corresponding MessageListeners for a single queue. If one of these MessageListeners receives a message but has not yet acknowledged it - is it possible that another MessageListener listening to that same queue could also receive that same message?

Answer to question 1 : Not shure but very doutfull.

Answer to question 2 : MQSeries will never deliver twice a message unless previously rollbacked from another connection or the same one.
