Hi I think the definition of these terms are:
The JMSXGroupId header Guarantees ordering of the processing of related messages across a single queue. nonBlockingRedelivery option controls whether on a Rollback of the session the messages that were previously delivered and will be re-delivered should block the delivery of new incoming messages. I was wondering if these concepts can be used together with a single consumer to block messages (and leave them on the queue) of the same JMSXGroupId if there is a problem with one message, but let through messages belonging to other JMSXGroupIds? thanks in advance -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
