[jboss-user] [Clustering/JBoss] - Can't get JBoss to use custom loadbalancer

I need to write a custom loadbalancer or interceptor to route EJB requests to different servers in the cluster. The problem is I can't get JBoss to use my LB. Anyone have an idea? I am thinking maybe jboss can't find my class and therefore doesn't use it. If this is the case, where should I put the LB class?

section of jboss.xml for the clustered (stateless) bean:

  | <cluster-config>
  |         <partition-name>MyPartition</partition-name>
  |         <bean-load-balance-policy>
  |           com.acme.MyCustomBalancer
  |         </bean-load-balance-policy>
  |         <home-load-balance-policy>
  |           com.acme.MyCustomBalancer
  |         </home-load-balance-policy>
  |       </cluster-config>

And the simple LB I try to use for testing

  | public class MyCustomBalancer extends FirstAvailable {
  |   @Override
  |   public Object chooseTarget(FamilyClusterInfo clusterFamily, Invocation routingDecision) {
  |     System.out.println("AAAAAAAAAAA");
  |     //List targets = clusterFamily.getTargets();
  |     return super.chooseTarget(clusterFamily, routingDecision);
  |   }
  | }
