quand j'execute les 2 classes à part,ça marche.
Maintenant que veux créer 2 autre fenetres dans chacune un boutton.
j'ai mis un écouteur sur chaque boutton et au clique j'instancie la classe serveur

Code:

Ser2 x=new Ser2();

ou client

Code:

Cli2=x new Cli2();

à l'execution,j'ai mes 2 nouvelles fenetres,mais dès que je clique sur les boutton pr avoir les fenetre Cli2 et Ser2,ça bloque!!!!qlq1 peut me dire pk?
