Problème lancement web start: java web start error null

**Valkirion** · 29/07/2008, 11h19

Bonjour!

J'ai un petit problème ( enfin, petit, tout est relatif

). Je tente de lancé une application java en web start. J'ai configure mon jnlp comme suit :

Code :

Mais quand je veux lancé l'application, le web start la charge, affiche l'écran d'ouverture, mais plante ensuite l'application. (l'application doit se connecté sur un programme qui tourne en mode serveur, je sais pas si c'est une cause ou pas). APres avoir un peu farfouillé le code et fais quelque print, on a pu voir qu'il plantait au niveau du chargement d'une constante statique. Mais si on change la version du jdk et jws ( 1.6 tt les 2 pour le moment), et qu'on passe en 1.5, le probleme semble se poser ailleur
