Issue looking up session bean in UDP

[joydeep.sarkar]

Dear All,

I am trying to look up a session bean which is configured in UDP cluster in JBoss5.1.0GA.
I am using EJB 3 and JDK 5.

Following is the client code,

package client;  

import test.session.HelloSession;  

import test.session.HelloSessionBean;  

import javax.naming.Context;  

import javax.naming.InitialContext;  

import javax.naming.NamingException;  

import java.util.Properties;  

public class TestMasterSlave {  

        public static void main(String[] args) {  

            Properties properties = new Properties();  

            properties.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");  

            properties.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");  

            properties.put("java.naming.provider.url","224.0.0.2:9876");  

            Context context;  

           try{  

               context = new InitialContext(properties);  

               System.out.println(context.getEnvironment());  

               HelloSession helloSession = (HelloSession) context.lookup("remote/HelloSession");  

              helloSession.sayHello();  

           } catch (NamingException e){  

               e.printStackTrace();  

           }  

       }  

} 

I have used multicast address as provider url and the client is also inside the UDP network. Now when I run the client I get the following error,

Exception in thread "main" java.lang.IllegalStateException: Failed to find method for hash:-790108502850547550 available={-884175917852741154=public abstract java.lang.Object org.jnp.interfaces.Naming.lookup(javax.naming.Name) throws javax.naming.NamingException,java.rmi.RemoteException, -5642140585403320990=public abstract java.util.Collection org.jnp.interfaces.Naming.listBindings(javax.naming.Name) throws javax.naming.NamingException,java.rmi.RemoteException, -4221607359560216057=public abstract java.util.Collection org.jnp.interfaces.Naming.list(javax.naming.Name) throws javax.naming.NamingException,java.rmi.RemoteException, -5717908715153450081=public abstract void org.jnp.interfaces.Naming.rebind(javax.naming.Name,java.lang.Object,java.lang.String) throws javax.naming.NamingException,java.rmi.RemoteException, -8107796390111393345=public abstract void org.jnp.interfaces.Naming.unbind(javax.naming.Name) throws javax.naming.NamingException,java.rmi.RemoteException, -7286638714004764603=public abstract javax.naming.Context org.jnp.interfaces.Naming.createSubcontext(javax.naming.Name) throws javax.naming.NamingException,java.rmi.RemoteException, -6149798079139202860=public abstract void org.jnp.interfaces.Naming.bind(javax.naming.Name,java.lang.Object,java.lang.String) throws

I am not sure what exactly is causing the issue. Is the UDP lookup as same as JNDI from a client code?
Could anyonep please help me on the same?
