Bonjour,
Je bosse sur un projet J2EE,EJB3 avec Jboss AS 5.1.
Depuis que j'ai lié mon serveur d'application Jboss à une BD Mysql, j'obtiens cette erreur quand j'appelle des méthodes de mes sessionBean:
TransactionRequiredException: EntityManager must be access within a transaction.




Je n'utilise pas de transaction et toutes mes session Bean sont stateless.
Quelqu'un pourrait m'expliquer?
Merci


Voila la trace de l'exception

Apparemment cette discussion est résolu mais personnellement j'ai le même problème et je ne trouve pas la solution.
Est ce que quelqu'un pourrait m'aider?

Merci d'avance
