Test d'intégration EJB 3.1, JPA 2, Weblogic 12.1.2, No EJBContainer provider available
Bonjour tout le monde,
Je suis en traine de développer une petite application en utilisant EJB 3.1, JPA 2.0.
Le serveur est Weblogic 12.1.2, et je dispose d'une petite base de données Oracle.
Voici l'EJB à tester :

pour le embedded EJB container j'ai ajouté le jar weblogic.jar au classpath de l'application.
Après exécution j'obtiens l'erreur suivante :
