[jboss-user] [JBoss Messaging] - Re: Redelivery order

[timfox]

If you rollback a transaction in which you have consumed three messages A, B, C, then the order will indeed be preserved on rollback with JBM.

However if you rollback each message in it's *own* transaction, then I don't think it's physically possible to guarantee any order.

Rollback just puts the messages back on the front of the queue. So it's the order is always going to depend on timing.

BTW the JMS spec does not require order of delivery to be preserved after rollback anyway.
