Jar exécutable + JOGL

[Résolu]Jar exécutable + JOGL

Bonjour,

J'ai codé un truc en JOGL et j'aimerai en faire un jar exécutable et portable au moins sous GNU/Linux, Mac OS et Windows. Je travaille avec Eclipse. Quand j'exporte le projet en jar exécutable, il ajoute bien les jar de jogl mais pas les librairies natives. J'ai essayé en les ajoutant moi-même dans le jar mais ça ne donne rien. Pourriez-vous m'aider?? Merci!

Salut

J'ai essayé en les ajoutant moi-même dans le jar mais ça ne donne rien.

Ne les mets pas DANS le jar, mais à côté, dans le même répertoire. Normalement ça devrait être bon.

J'ai essayé mais ca ne va pas.

:(:(:(

solution

Finalement en les mettant dans un dossier connu ou en les mettant dans le même dossier comme le disait plegat, ça marche mais a condition de lancer le jar en console avec cet argument :

Code:

java "-Djava.library.path=chemin_des_librairies" -jar programme.jar

voilà
