Je développe un portlet qui utilise des classes hibernate.
Au déploiement de mon portlet, la méthode init est appelée.
J'ai mis le code suivant dans init :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

EntityManagerFactory emf = Persistence.createEntityManagerFactory("annotation");
        EntityManager newEm = emf.createEntityManager();
        EntityTransaction newTx = newEm.getTransaction();
        newTx.begin();
        List users = newEm.createQuery("from User").getResultList();
        System.out.println( users.size() + " user(s) found" );
        newTx.commit();
        newEm.close();
        // Shutting down the application
        emf.close();

Sauf que quand cette méthode init est appelée, j'ai une grosse erreur.
Je pense que j'ai juste pas bien placé mes fichiers persistance.xml et hibernate.cfg.xml.

Voilà ce qui sort en console :

Effectivement j'avais mal placé mes fichiers pesistence.xml et hibernate.cfg.xml.
Il faut les placer dans webapp/META-INF tous les deux.

Ensuite, il faut s'assurer que le conteneur de portlet a bien les bonnes lib pour la persistence (les libs hibernate mais aussi le driver de base de données que vous utilisez).
