Still a very simple example of enterprise application.

I use NB 6.8rc1.

Server side:

package ice.server;

import javax.ejb.Remote;

@Remote
public interface ServerBeanRemote {
    public int add(int a, int b);
}

package ice.server;

import javax.ejb.Stateful;

@Stateful
public class ServerBean implements ServerBeanRemote {

    public int add(int a, int b) {
        return a + b;
    }
}

Client side:

package ice.client;

import ice.server.ServerBeanRemote;
import javax.ejb.EJB;

/**
 *
 * @author lnx
 */
public class Client {
    @EJB
    public static ServerBeanRemote server;

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        System.out.println(server.add(2, 3));
    }

}

I build and deploy it. no problem. But when I run it, following error comes out:

Undeploying ...
