Hi all,

I'm new to EJB.  I'm writing a toy EJB, and having problem running the client (bean can be deployed successfully in Eclipse)  When running the client, it generates javax.naming.NameNotFoundException: HelloBean not bound. 

Please help.  THANKS A LOT!!!

my config:
IDE: Eclipse
JBOSS: 4.0.5

//INTERFACE:
package examples.session.stateless;
import javax.ejb.*;
public interface Hello {
	public String hello() ; //throws java.rmi.RemoteException;
}


//BEAN CLASS
package examples.session.stateless;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.ejb.*;
@Stateless
@Remote(Hello.class)
public class HelloBean implements Hello {	
	  public String hello () {
		  System.out.println("in hello()...");
		  return "Hello, World!";
	}
}

CLIENT
package examples.session.stateless;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;

public class HelloEJBClient {
	   public static void main( String [] args ) 
	   { 
	     Hashtable env = new Hashtable(); 
	     env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); 
	     env.put(Context.PROVIDER_URL, "localhost:1099"); 
	     env.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces"); 
	    
	     try 
	     { 
	       InitialContext ctx = new InitialContext(env); 
	       Hello hello = (Hello) ctx.lookup( "HelloBean" ); 
	       System.out.println(hello.hello()); 
	     } 
	     catch ( Exception e ) 
	     { 
	       e.printStackTrace(); 
	       System.out.println( "Chen - Exception: " + e.getMessage() ); 
	     } 
	   } 
}
