Hi, I have an application scenario where it is neccessary that subscribers know when they are successfully subscribed.
1. Is there a mechanism available in ActiveMQ (I couldn't find any) or do I have to implement some kind of request/reply between subscribers and publishers (like: "plz send a dummy notification to my topic"->"dummy notification"->"ok, I'm subscribed")? Another solution could be implemented with advisory messages. A subscriber first subscribes to the predefined advisory topic, then to his topic of interest and then waits until he receives the advisory notification regarding his topic subscription. However, the documentation of advisory messages does not define precisely when an advisories message is created. 2. Is the advisory message created when a subscription message is received by a broker or when a subscription is actually active (i.e. effected the data-structures on the broker, is part of the notification matching process)? This problem is even more sever if you have a network of brokers where it can take some time until a subscription is active. I think acknowledgments are needed because otherwise a subscriber cannot decide whether he receives no notifications because there are none or because his subscription failed. I'm interested in your thoughts and suggestions regarding subscription acknowledgments with JMS.
