[jboss-user] [Clustering/JBoss] - Re: How can I deploy a MDB to only one instance in a cluster

[justkeys]

Annotate with

@Depends("jboss.ha:service=HASingletonDeployer,type=Barrier")

If you want only one instance within the jvm, also annotate with

@MessageDriven(activationConfig = { 		@ActivationConfigProperty(propertyName = "maxSession", propertyValue = "1")})

A second node in the cluster will not run this mdb, till the first master node goes away.
