Il faut simplement setter le TableModel. Voir la fin de la méthode.

Par contre ta gestion d'exceptions n'est pas optimale, tu risques, en cas d'erreur d'exécution, de laisser des choses ouvertes. Les appels aux méthodes close doivent se faire dans des blocs finally.

merci bcq mon frere :lol:

le code a bien marche méme si il me donne un ereur dans cette partie

Code:

Logger.getLogger(Transport.class.getName()).log(Level.SEVERE, null, ex);

il me dit qu'i ne trouve pas le symbole
symbol :method log(java.util.logging.level,<nulltype>,ex)

et cannon't find symbole

variable :"ex "

je sais pas ou le probleme :(

et merci encore

ex n'existe pas, probablement un erreur de copier coller, suffit de remplacer par le bon nom de variable ;)

Merci pour l'aide
:lol:
