[EJB3] Acces distant KO

Acces distant KO

Bonjour à tous,

j'ai un EJB de test(tout ce qu'il y a de plus simple) sur un serveur weblogic.

Lorsque j'y accède depuis une page de test que j'ai inclue dan l'ear ça marche, mais lorsque j'y accède depuis une classe avec un main (en dehors du serveur) j'ai une erreur.

Merci !! Je ne comprend pas ce que j'ai mal fait -_-''''

Merci de votre aide !!

Bonjour,

Citation:

java.lang.ClassNotFoundException: fr.TestRemote

La classe TestRemote n'est pas dans le classpath de l'application Main.

Même probléme

voici la trace :

Je pense avoir trouvé pour ceux qui rencontreront le probléme.

On se met sur la classe qui contient le main dans eclipse.
Click droit => Run as/Debug as => Run Configurations / Debug Configurations.
On va sur l'onglet ClassPath on ajoute wlClient.jar dans User Entries, on supprime les libs weblo si il y en a (Weblogic System Library) et normalement ça devrait marcher.
