Hello ,

I am using JBoss [Zion] 4.0.3RC1.Here is the code of my session bean

Home Interface
------------------
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;

public interface AdviceHome extends EJBHome{
public AdviceComponent create() throws  RemoteException,CreateException;
}

Component Interface
-------------------------
package com.fritolay;

import java.rmi.RemoteException;
import javax.ejb.EJBObject;

public interface AdviceComponent extends EJBObject{
	public String getAdvice() throws RemoteException;
}

Bean class
--------------
package com.fritolay;

import java.rmi.RemoteException;

import javax.ejb.EJBException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;


public class AdviceImpl implements SessionBean{

	public void ejbActivate() throws EJBException, RemoteException {
		// TODO Auto-generated method stub
		
	}

	public void ejbPassivate() throws EJBException, RemoteException {
		// TODO Auto-generated method stub
		
	}

	public void ejbRemove() throws EJBException, RemoteException {
		// TODO Auto-generated method stub
		
	}

	public void setSessionContext(SessionContext arg0) throws EJBException, RemoteException {
		// TODO Auto-generated method stub
		
	}
	
	public void ejbCreate(){
		System.out.println("ejbcreate method called...");
	}
	public String getAdvice(){
		return "No Advice Temporirly";
		
	}
}



Client code
----------------
package com.fritolay;

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

public class AdviceClient {

	
	public static void main(String[] args) {
		InitialContext context = null;
	    try {
	    	
	    	java.util.Hashtable JNDIParm = new java.util.Hashtable();
	JNDIParm.put(Context.INITIAL_CONTEXT_FACTORY,        "org.jnp.interfaces.NamingContextFactory");
			 JNDIParm.put(Context.URL_PKG_PREFIXES, "org.jnp.interfaces");
			JNDIParm.put(Context.PROVIDER_URL, "localhost:1099" );
	    	context = new InitialContext(JNDIParm);
	    	
	    	if(context==null){
	    		System.out.println("Context is Null");
	    	}
	    	else
	    	{
	    		System.out.println("Context is Not Null");
	    	}
	    	Object o=context.lookup("kamini");
	    	AdviceHome hec=(AdviceHome)PortableRemoteObject.narrow(context.lookup("kamini"),AdviceHome.class);
	    }
	    catch(Exception e){
	    	e.printStackTrace();
	    }

	}

}
