When I try to run EJBclient on remote system I get the following exception

Question

Hi all,
I try to run EJB's sample,system is Windows XP,J2SDK1.3.1,J2EE1.3,code is:
Properties env = System.getProperties();
env.putContext.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL, "iiop://ysmlj:1050");
env.setProperty("org.omg.CORBA.ORBInitialHost","ysmlj");
Context initial = new InitialContext();
Object objref = initial.lookup("HelloWorld1");
HelloWorldHome home = (HelloWorldHome)PortableRemoteObject.narrow(objref, HelloWorldHome.class);
HelloWorld helloWorld = home.create();
helloWorld.sayHello();
But on remote system run this Client,I get exception is
org.omg.CORBA.COMM_FAILURE: minor code: 1398079490 completed: No

This minor code error may due to different version of JVM in your server and clients. I had same error when i change client JVM version with server version i could solve the problem..
          properties.put(javax.naming.Context.PROVIDER_URL,"iiop://server:1050");
          properties.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.cosnaming.CNCtxFactory");
          InitialContext ic = new InitialContext(properties);
          Object objref = ic.lookup("lookup name");
