Topics are persisted only if they are durable (that is, a durable listener has registered with the topic). Non-durable messages to a topic are distributed immediately to all current topic listeners (or dropped if there are none).
Correct me if i'm wrong.
Topics are durables only if i have a cluster system ?
Hi, It is nothing to do with cluster. Durable means you have created one or more durable subscribers to the topic. You can check out the details in the JMS spec 1.1.
