Are there any standard j2eepatterns for guaranteed message delivery. I know that we can use JTA and JMS retry mechanism to achieve that. But looking for some tried and tested patterns/solutions.
I am trying to design a system which accepts message from an upstream application, processes it and sends it to another downstream system. The downstream application ensures guaranteed delivery (they seem to be using a persistent queue). I want to ensure that the message is not lost while my application works on it and ensure 100% delivery to my target downstream system.
