Exception while dispatching incoming RPC call

Bonjour,

Je développe une petite appli de gestion de stock et je suis bloqué sur un problème de communication client / server.

- J'utilise Eclipse java EE + glassfishV3 + hibernate + une bdd postgresql.
- J'ai généré mes EJB avec netbeans.
- J'utilise le modèle MVP.
- J'ai 3 projets, l'EAR, les EJB, et le WEB project.

Je ne sais pas trop quoi préciser de plus. :aie:

J'ai pas mal cherché sur le net, mais je trouve vraiment pas grand chose concernant ce problème, et sur gwt en général :cry:, malgré la relative fréquence du problème.

Si vous avez une idée, merci d'avance. :ccool:
