Bonjour,

J'ai une application Java3D lancée deuis un jnlp qui marchait bien jusqu'à présent depuis le Web.
Avec Java 7 cela bug. (enfin je suppose que c'est depuis la jre7 ...)

Voici un extrait de la console Java :

La solution que j'ai trouvé pour l'instant c'est de mettre dans le ../jre/lib/ext les 3 librairies Java3D, à savoir : j3dcore.jar, j3dutils.jar et vecmath.jar.


Théoriquement mon jnlp devrait les avoir télécharger ...

Voici mon jnlp :

Avez-vous une idée du problème ?

PS : j'ai bien signé tous les jar de ce jnlp
