[Eclipse exportation d'un .jar executable] Problème de librairie

Bonjour.

Je travail sous eclipse et mon programme tourne très bien dessus.
J'ai importer les librairies pour pouvoir utiliser opengl dans mon programme.
Mais, quand j'exporte mon programme dans un .jar executable, j'ai des erreurs à l'execution :

Eclipse me produit ce manifest :
Manifest-Version: 1.0
Rsrc-Class-Path: gluegen-rt.jar jogl-natives-win32.jar jogl.jar
Class-Path: .
Rsrc-Main-Class: Fenetre
Main-Class: org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader

Quelqu'un pourrait m'éclairer ? :?

Merci.
