What are my options for the following requirement: Step 1: A consumer gets a message from a broker's queue (which will likely use roundrobin). Step 2: It realizes that it doesn't want this particular message at this time, so the broker should deliver it to another consumer.
Transacted sessions are the only real way to undeliver a message; but then the JMS client will replay the messsage N times before its really failed back to the broker (based on the RedeliveryPolicy). You could just wait until the time is right to be able to consume the message? Generally speaking, its considered bad form to consume messages then realise they're not for you and try to un-deliver them. You really should use selectors to filter out what you need. If for whatever reason you can't use selectors then you should place the message on a different queue for 'someone else' to process (so that its then easy to filter out yourself from getting the message again). i.e. using the the 'undeliver' approach its very easy for messages to be continuously delivered to the wrong consumer & cause loads of unnecessary work. -- James ------- http://macstrac.blogspot.com/
