Got a question about the pub/sub messaging model in JMS. Let's say there is a subscriber who has subscribed to a topic. The subscriber disconnects. Later he reconnects and resubscribes to the same topic. In which of the following scenarios will the subscriber get the messages that he missed when he was disconnected?
The missed messages are PERSISTENT and the subscriber has a DURABLE subscription - Yes The missed messages are NON-PERSISTENT and the subscription is DURABLE - No PERSISTENT messages and NON-DURABLE subscription - No NON-PERSISTENT messages and NON-DURABLE subscription - No
So the subscriber will get the missed messages ONLY if the messages are PERSISTENT and his subscription is DURABLE. Is my understanding right? Are there any exceptions to be considered? Please clarify
