comment redimensionner la fenêtre de l'applet jws?

Question

J'utilise JWS pour démarrer mon application. J'ai besoin de réinitialiser ma taille de JFrame et il ne devrait pas être redimensionné. J'ai essayé avec frame.setSize(new Dimension(500, 500)); et frame.setResizable(false); qui ne fonctionne pas. J'ai traversé le forum et essayé d'autres options disponibles. Mon code complet est

Appel pack() va changer la taille au minimum requis pour adapter le contenu de l'interface utilisateur placé dans cette fenêtre. Si nous supprimons cette ligne, les dimensions doivent rester là où vous les avez définies.

private void launchApplication() { 
    /* other code omitted */ 
    panel.setBorder(new EmptyBorder(8, 8, 8, 8)); 
    setSize(dimension); 
    setResizable(false); 
    getContentPane().add(panel);   
    //pack(); 
}
