[jboss-user] [JBoss Messaging] - MDB and clustered Topics

I've tried to answer this question myself through forms and the documentation but I've been unable (probably due to my own misunderstanding). Env: JBoss 4.2.2 JBoss Messaging 1.4.0.SP1 I have a node of 3 servers, and I'm deploying the same ear to all 3. In that ear I have a MDB that consumes from a topic using a durable subscription where I specify the sub name and client id. So what this means is that each server has an instance of the MDB that consumers from a topic using the same sub name and client id. My question is should this topic be clustered? When a message is posted to the topic I only want 1 of the mdb instances in the cluster to get a copy, not one on all 3 machines? Thanks in advance. ~Jonathan View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4117112#...
