    Connect to Mbean using RMI Connector

    stephen Newbie

      Hello,

      I try to connect to Mbean using the RMI Connector. From the stack trace seems it require Sun JMX implementation. whereas i am using JBoss JMX implementation. I am confused why It required com/sun/jmx/mbeanserver/GetPropertyAction.

      Below is the code i used to invoke the mbean. I have jbossall-client.jar in my classpath.


      public static RemoteMBeanServer getMBeanServer(){
      String jndiName = "jmx/rmi/RMIAdaptor";
      RemoteMBeanServer server = null;
      try{
      Context context = initContext();
      if(context != null){
      RMIAdaptor adaptor =
      (RMIAdaptor)context.lookup(jndiName);
      server = new RMIConnectorImpl(adaptor);
      }
      }catch(NamingException ex){
      System.out.println("can't find the adapter");
      //ex.printStackTrace();
      }
      return server;
      }

      public static Context initContext(){
      Context context = null;
      String jndiUrl = "jnp://172.16.0.112:1099";
      try{
      Properties props = new Properties();
      props.setProperty(Context.PROVIDER_URL,
      jndiUrl);

      props.setProperty(InitialContext.INITIAL_CONTEXT_FACTORY,
      "org.jnp.interfaces.NamingContextFactory");
      props.setProperty (Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
      context = new InitialContext(props);
      }catch(NamingException e){
      e.printStackTrace();
      }
      return context;
      }
      public static Object invokeOpByName(String name, String method,
      Object [] args, String [] argsType)
      throws MalformedObjectNameException,
      NullPointerException,
      InstanceNotFoundException,
      MBeanException,
      ReflectionException {
      Object ob = null;
      RemoteMBeanServer server = getMBeanServer();
      if(server != null){
      ObjectName objectName = new ObjectName(name);
      ob =
      server.invoke(objectName,method,args,argsType);
      return ob;
      }
      }

      Any helps are very much appreciated. thanks

      Regards,
      Stephen
