What is meant by the question as "default acknowledgement mode"?

[admin]

In this question, since the message needs to be sent in a transaction, the first parameter is has to be true and so the second parameter will be ignored. So only option 4 is correct.

This explanation has been added to the question.

thanks for your feedback!

According to the spec (13.3.5):

Because the container manages the transactional enlistment of JMS sessions on behalf of a bean, the parameters of the createSession(boolean transacted, int acknowledgeMode), createQueueSession(boolean transacted, int acknowledgeMode) and createTopicSession(boolean transacted, int acknowledgeMode) methods are ignored. It is recommended that the Bean Provider specify that a session is transacted, but provide 0 for the value of the acknowledgment mode.

I tried both cases in GlassFish 3.1 (setting both true and false to the transacted parameter), and it seems to confirm that the transacted flag is ignored. Whether or not the message is sent successfully depends on the outcome of the bean transaction and has nothing to do with the transacted flag. Any clarifications you can provide is much appreciated!

You are right but it applies only to beans. The question is not talking just about the beans.
