Hi I am new bie,

The stateful bean and Interface are as follows.
-----------------------
package business;

import java.util.Collection;
import javax.ejb.Remote;

@Remote
public interface Cart {
public void addItem(String item);
public void removeItem(String item);
public Collection getItems();
public void listItem(Collection stuff);
}
------------------
package business;

import java.util.ArrayList;
import java.util.Collection;
import javax.annotation.PostConstruct;
import javax.ejb.Stateful;
import javax.ejb.Remote;
import java.util.Iterator;

@Stateful(mappedName="CartEJB")
@Remote(Cart.class)
public class CartBean implements Cart {
private ArrayList items;
private Collection stuff;
@PostConstruct
public void initialize() {
items = new ArrayList();
}

public void addItem(String item) {
items.add(item);
}

public void removeItem(String item) {
items.remove(item);
}

public void listItem(Collection stuff) {
for (Iterator i = items.iterator(); i.hasNext() {
String item = (String) i.next();
System.out.println(" " + item);
}
}

public Collection getItems() {
return items;
}
}
-------------

The jar built with these 2 is succesfully deployed in JBoss

When a standalone client tried to access the CartBean with the mappedname attribute it gives the below exception

javax.naming.NameNotFoundException: CartEJB#Cart not bound

I am using lookup like this

ctx.lookup (CartEJB#Cart)

Not sure if I have to make the request in JBoss forum. Please advice

It is sorta covered in the JavaRanch Style Guide.
