javax.persistence.PersistenceException: No Persistence provider for EntityManager named poc-gui-jpa: Provider named org.hibernate.ejb.HibernatePersistence threw unexpected exception at create EntityManagerFactory:

J'ai l'impression qu'il n'arrive pas à trouver mon persistence-unit.

Pourriez vous m'indiquer mon erreur?

JE vois que tu as plusieurs persistence.xml... Que contient le persistence.xml de ton dossier de test ?

Vas aussi voir dans le dossier target pour voir si ton persistence.xml est bien déployé.
