Erreur : javax.persistence.PersistenceException: No Persistence provider for EntityManager named
Bonjour,
je soupçonne que mon fichier "persistence.xm"l soit la cause du problème mais je n'arrive pas à trouver.
Celui ci est placé dans "poc-gui-dao\src\main\resources\META-INF\persistence.xml"
Pourriez vous me donner un peu d'aide?
