[jboss-user] [Management, JMX/JBoss] - Migration issues from previous versions(JBOSS 3.2.x) to JBOS

I have made an application which is clustered enabled. but i am facing few issues while porting it onto jBOSS4.0.5, its perfectly running in JBOSS-3.2.6 1-HARMIProxyCallBack interface not found, in JBOSS-4.0.5 what is the alternate of it. i had RMIListnerMBean which is extends ServiceMBeanSupport and implements HARMIProxyCallback and in the start Service Method i was doing something like String fullPartitionName = "/HAPartition/DefaultPartition"; context = new InitialContext(); partition = (HAPartition) context.lookup(fullPartitionName); // Create a clustered Proxy/stub msghandler = new MyMessageHandler();//my own class extending the Listner Class myHARMIServer = new HARMIServerImpl(partition, "RmiMessageServer", Listener.class, msghandler, 0, null, null, null, this); stub = myHARMIServer.createHAStub(new RoundRobin()); rebind(); should i port this code other way..? to make it compatible with JBOSS4.0.5 2-getting error while invoking on context = new InitialContext(); adaptor = (RMIAdaptor) context.lookup("jmx/rmi/RMIAdaptor"); ObjectName objName = new ObjectName("txt:config=Core"); Object obj = adaptor.invoke(objName, "getCoreDBSource",null, null); this piece of code is working fine in 3.2.6 version. i read somewhere that in new versions we should use MBeanServerConnection instead of RMIAdaptor i used it but still getting exception: javax.management.ReflectionException at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInv is there any need... to extend MBean from certain classes or implement any interface? my MBean is very simple.. extending HAServiceMBeanSupport and implementing NotificationListener.
