[jboss-dev-forums] [Design of JBoss ESB] - Re: Failover MessageRedelivery

[kurt.stam@jboss.com]

Well this should not happen between actions in the pipeline, but only when routing between services. The code base is now refactored (well almost) to always use the ServiceInvoker for sending messages between services. Now look at the code in asyncDelivery:


  |  message.getProperties().setProperty(MessageStore.CLASSIFICATION, MessageStore.CLASSIFICATION_RDLVR);
  |                 message.getProperties().setProperty(DELIVER_TO, service);
  |                 deliverToDeadLetterService(message);
  | 

If delivery fails it sets the TO service in a property as well as telling it to store it in the MessageStore under classification RDLVR. 

Now the Redeliver Service periodically wakes up and tries to redeliver all the messages in the RDLVR classification. It uses the setting for the TO service to figure out where to send it. Note that this is bound to the service address and not the EPR. For each retry it will pull the latest EPR information for that service.

Going to work on making the maxRedeliveries configurable now :).

Does that help?
