I have Session bean in com.mysession package
Session Bean Name:vMySessionBean
Home interface: MySessionBeanHome
Remote interface: MySessionBeanRemote

MyClient class as follows

import java.util.Hashtable;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;

import com.mysession.MySessionBeanHome;
import com.mysession.MySessionBeanRemote;


public class MyClient {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
   try{
	  Hashtable ht=new Hashtable();
	  ht.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
	  System.out.println("xxxxxxxxxxxxxxxxxxxxxx");
	  ht.put(Context.PROVIDER_URL,"jnp://localhost:8080");
	  System.out.println("yyyyyyyyyyyyyyyyyyyyy");
	  ht.put("java.naming.factory.url.pkgs", "org.jboss.naming");
	  System.out.println("zzzzzzzzzzzzzzzzzzzzzzzzz");
	   Context ctx=new InitialContext(ht);
	   	   
	   //ctx.bind(java:/comp/env,MySessionEJB);
	   System.out.println("aaaaaaaaaaaaaaaaaaaaaaaaa");
	   //Context ic=(Context) ctx.lookup("java:comp/env");
	   Object obj=ctx.lookup("java:comp/env/MySessionEJB");
	   System.out.println("after lookup");
	   MySessionBeanHome msbh=(MySessionBeanHome)PortableRemoteObject.narrow(obj,MySessionBeanHome.class);
	   MySessionBeanRemote msbr=msbh.create();
	   msbr.sayHello();
   }
   catch(Exception e){
	 e.printStackTrace();  
   }
	}

Since client and JBoss are running in different VMs, client will not have access to the "java:/" and "java:comp/env/" namespaces.
Just use

  Object obj=ctx.lookup("ejb/MySessionEJB");
