Conversion JFrame

Bonjour,

J'ai une application autonome en Java que je voudrais lancer à partir d'une page internet (donc en applet).
J'ai déjà trainé beaucoup (et longtemps) sur internet pour trouver des réponses à mon problème.

J'ai vu entre autres, qu'il faudrait:
- déplacer la méthode main(String arg[]) dans la classe de la JFrame
- changer "public static void main(String arg[])" en "public void init()"
- changer JFrame en JApplet (et donc importer "javax.swing.JApplet")
etc...

Il paraitrait que c'est "facile", mais je ne m'en sors pas du tout !

Voici les 2 fichiers principaux (je lance Run.class):

Code:

1

public class Run
{
 public static void main(String[] args)
  { MainScreen mainscreen1 = new MainScreen();
    mainscreen1.show();
  }
}
