    Cluster Impl Module loaded from different module loader

    sudhananthan B Newbie

      Hi,

      I'm using jboss EAP 6.1.0.

      In Cluster Singleton service GroupMembershipListener listener has been added as below,

       

      ServiceController<String> controller =  singletonService.build(CurrentServiceContainer.getServiceContainer())
                      .addDependency(ServiceName.JBOSS.append("cluster", "singleton"),
       GroupMembershipNotifier.class, myHAsingletonService.getEnvInjector()).install();
      

       

      Inside the overided membershipChanged method of my SingletonService I've used class belongs to module org.picketbox module. Due to which following exception occurs

      I can resolve it by adding the dependency of org.jboss.as.clustering.impl in jboss-deployment-structure.xml and doing the same operation which i did in membershipChanged method in MDBean. Even in MDBean i get the same exception if i remove the org.jboss.as.clustering.impl dependency in jboss-deployment-structure.xml.

       

      Anyone tell me why this occurs.

       

      Thanks in Advance,
