    Problem in accessing JNDI over HTTP

      Iam facing a timeout problem when trying to access JBoss JNDI over HTTP.
      Have any come come across this issue???????. If so please help...

      The details are given below

      Requirement:

      Need to access RMIAdaptor by doing JNDI naming service lookup over HTTP. Followed the steps specified below.
      http://docs.jboss.com/jbossas/admindevel326/html/ch3.chapter.html#ch3.accessingjndi

      JBoss System information:
      JBoss version: 4.0.2
      JBoss have multiple ip. One internal ip and another external ip. Only the internal ip is visible to the JNDI Client program.

      Modification done in http-invoker.sar:

      I modified jboss-service.xml and replaced InvokerURLPrefix,InvokerURLSuffix and UseHostName with single attribute InvokerURL pointing to http://internalidp:8080/invoker/...InvokerClass..

      The JBoss client program is given below

       public static void main(String args[]) throws Exception
 {
String host = args[0];
 String port = args[1];
 Properties env = new Properties();
 env.setProperty(Context.INITIAL_CONTEXT_FACTORY,
 "org.jboss.naming.HttpNamingContextFactory");
 env.setProperty(Context.PROVIDER_URL,
 "http://"+host+":"+port+"/invoker/JNDIFactory");

 Context ctx = new InitialContext(env);
 System.out.println("Created InitialContext, env=" + env);

 Object data = ctx.lookup("jmx/invoker/RMIAdaptor");
 System.out.println("lookup(jmx/invoker/RMIAdaptor): " + data);
 // System.out.println("Obtained : " + data.getClass().getName());
 System.out.println("Total number of MBeans in JBoss server : "+((org.jboss.jmx.adaptor.rmi.RMIAdaptor)data).getMBeanCount());
}


      The above code looksup MBeanServer. The below exception appears while doing the lookup opertaion 
      Operation failed [Root exception is java.rmi.ServerException: IOE;
nested exception is:
 java.net.ConnectException: Connection timed out]

      Please note that Iam able to access internalip:<jboss port> from the machine in which my client program is running.

      Additional Information:

      Iam able to access http://<JBoss internalip>:8080/invoker/JNDIFactory from the client machine.

      The complete trace is given below
