Using JMS Gateways on Topics in a Clustered environment using JBoss-ESB

Issue

• We have two ESB services listening (through a gateway) to a JMS topic, it has been done this way because we would like to add new services in the future listening in the same topic and we want to avoid having one queue for each service and a static route with the list of all services.
• This works fine if we are using a single ESB instance, but if we run in a cluster (with JBoss Messaging configured for clustering) the messages are processed by the services in all the nodes, so we are processing the same message multiple times.
• Is there a way to avoid this behavior and have a message processed only by a single instance of the service?
