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

[jduty]

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.
