[Java] Probleme lors de l'exécution du .jar

[Ben017]

Bonsoir,

Je viens de finir mon petit programme java, je crée le .jar, mais au moment de l’exécution, mon programme ne se lance pas, et la console windows s'ouvre et se ferme instantanément avec le message :

Exception in thread "main" java.lang.NoClassDefFounfError: C:\***
Caused by : java.lang.ClassNotFounfException: C:\***.jar
              at java.net.URLClassLoader$1.run<Unknow Source>
              at java.security.AccessController.doPrivileged<Native Method>
              at java.net.URLClassLoader.findClass<Unknow Source>
              at java.lang.ClassLoader.loadClass<Unknow Source>
              at sun.misc.laucher$AppClassLoader.loadClass<Unknow Source>
              at java.lang.classLoader.loadClass<Unknow Source>
Could not find the main class: C:\***.jar.     Program will exit.

Voila, je reste bloqué devant cette console depuis ce matin, j'ai bien essayé les quelques résolutions trouvées sur le net, mais en vain...
Si quelqu'un a une petite idée.

Par avance merci.

P.S. voici une partie de mon code :

et Voici la Class Main

import Fenetre.Interface;
public class Main {
  public static void main(String[] args) {
   Interface inter = new Interface();
  } 
}
