Вот пытаюсь реализовать простой RMI Server Интерфейс | Код |

interface Product extends Remote{
String getDescription() throws RemoteException;

ProductImpl | Код |
import java.rmi.server.UnicastRemoteObject;

public class ProductImpl extends UnicastRemoteObject
implements Product {
public ProductImpl(String d) throws RemoteException{
descr = d;

public String getDescription() throws RemoteException{
return "I am a " + descr + ". Buy me!";
}
private String descr;
