générer un exécutable java

salut ..
j'ai essayé de générer un jar exécutable depuis netbeans, mais lors de la compilation par clean and build, il me donne l'erreur suivante:

Note: PrintPreview.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

comment pouvais-je corrigée ça??.
et merci d'avance.

ma class preinview:

Salut,

C'est juste une alerte et ça ne devrait pas empêcher le runnable de se faire. C'est simplement que tu utilises des classes paramétrées mais sans indiquer les paramètres, entre autres (comme ici par exemple : m_cbScale = new JComboBox(scales);. Pour corriger ces alertes dans le code, elles doivent être signalées dans ton éditeur, donc tu peux les trouver, regarder le message, et corriger (comme ça par exemple this.MAXIMIZED_BOTH). Mais il y a tellement d'horreurs (dont certaines que je t'ai déjà signalées et que tu as laissées sans vergogne) dans ton code, que tu peux bien laisser ces quelques warning :roll:

salut.
oui ça passe. je trouve l'exécutable dans le répertoire dist. mais il ne s'exécute pas, je sais pas pourquoi??

C'est-à-dire ne s'exécute pas ? Tu double-cliques sur le jar et rien, c'est ça ? Si tu n'as pas de logs, essaye en console java -jar tonjar.jar et tu verras s'il y a des exceptions (si tu les traces correctement du moins).

ça y est c'est bon..le problème c'était dans le chemin des icônes..

merci bien..;)
