No Persistence Provider !
Bonjour à tous.
Je viens à vous suite à ma perte de cheveux, me les tirant énormément... ; )
J'ai un une erreur de ce type :
Code:

javax.persistence.PersistenceException: No Persistence provider for EntityManager named jpaTerm |
J'ai vu grand nombre de site spécifiant telle ou telle solution, mais tout me semble correct ici et n'en trouve la fin !
Je travail sous Eclipse Helios, tomcat, Spring3, Jpa, Hibernate3
J'ai configuré mon fichier persistence.xml présent dans "META-INF/persistence.xml" (Il est bien présent dans mon Classpath)

A ce niveau de l'appel j'ai donc cette erreur
javax.persistence.PersistenceException: No Persistence provider for EntityManager named jpaTerm
J'ai essayé l'annotation : @PersistenceUnit(unitName="jpaTerm") mais rien ne se créé, j'ai un 'null' sur "factory";
Persitence.xml est bien trouvé, sinon j'aurai eus une erreur du style "FileNotFound" persistence.xml blabla
Par ailleurs, mes classes Entity "pays" et "continent" se sont bien créé au lancement du serveur.
INFO: Building JPA container EntityManagerFactory for persistence unit 'jpaTerm'
Et je les trouvent en base.
Je suis ouïe à toute suggestions : D !!
Merci de votre intérêt ; )
