Ok. I found the answer in ejb3 trailblazer. The trail on JMX Service Objects talk about how to annotate a service that depends on other services using @Depends tag. I guess the same holds true for EJBs as well, i.e. if an EJB depends on a service, use @Depends tag. I used following to make it work in my case: | ClusterStatusMBean clusterStatusMbean = null; | | @Depends ("myapp:service=ClusterStatus") | public void setClusterStatusMbean (ClusterStatusMBean mbean) { | this.clusterStatusMbean = mbean; | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4006938#...
