Problème Server RMI avec JAVA

Bonjour,

Je suis actuellement en train de faire un projet sous eclipse avec ServerRMI je me suis fait un .bat qui permet de lancer le rmiregistry.exe qui suis :

start rmiregistry
java ServerRMI
pause

et quand je lance ma classe ServerRMI qui est :

import java.rmi.*;
import java.rmi.registry.*;
import java.rmi.server.*;
import java.net.*;

public class ServerRMI {

static public void main(String args[]) {
try {
Naming.rebind("rmiServer", new RequestPDS());
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}
}
}

Il me sort l'erreur :
