Subject Re: Transactional Send Messages (NMS)
Date Tue, 03 Feb 2009 17:47:02 GMT
That sounds like a bug.  My understanding of how sessions work is if you
have set the AcknowledgementMode.Transactional, none of the messages that
you send to producers created on that session will be visible to any
consumers until the Commit() function is called.  At that point, all
messages sent up to that point will now become visible -- an all or nothing
proposition.  If this is not working correctly, can you provide some sample
code showing the problem?

Thanks,
Jim
