Well, I just tested an MDB with SwiftMQ, and Orion still stuffs up the message ordering. Presumably this means it's broken in the MDB implemenation rather than in Orion's JMS code, which is a pity.
So, for all those using Orion MDBs, and relying on message ordering being preserved (if there are any apart from me :-), please check out bug 729 in Bugzilla. It contains demo code to demonstrate the problem under both Orion JMS and SwiftMQ. http://bugzilla.orionserver.com/bugzilla/show_bug.cgi?id=729 Cheers, Geoff -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Geoff Soutter Sent: Monday, 18 February 2002 9:18 AM To: Orion-Interest Subject: RE: fyi: 1.5.4 still stacks rather than queues JMS messages Hi Mike, I didn't see that comment. Unfortunately this list is so flakey that I only get about 75% of the messages. I just checked the JMS 1.02 spec, here's what it has to say about message order (in 4.4.10.1 Order of Message Receipt): "JMS defines that messages sent by a session to a destination must be received in the order in which they were sent (see Section 4.4.10.2, "Order of Message Sends," for a few qualifications)." So it seems that, contrary to what that someone said, message order _is_ important with JMS.
