Bonjour
J'ai créé 2 fenêtres sous netbeans,la 1ère est une classe java qui se nomme "Login" et la 2nde se nomme "Accueil" et c'est une JFrame Form ,j'ai donc utilisé l'interface graphique de netbeans pour créer ma fenêtre "Accueil".Quand je lance mon application,la fenêtre login apparait.Si je clique sur le "ok" et que le login et le mot de passe sont bons,la fenêtre Accueil apparait.
Le problème est :
quand je crée le jar de mon projet(en faisant clean and build), le login apparait;mais quand je clique sur "ok",rien ne se passe.Pourtant sous netbeans tout marche bien.
J'utilise netbeans 6.8.
Voici mes 2 classes:
