[natoine]

Bon là je sais que ma pratique est mauvaise et j'aimerai faire propre.

Je recrée un EntityManagerFactory à chaque méthode ou je vais devoir faire des requêtes en Base.
Comment je peux dans une portlet ne créer qu'un seul EntityManagerFactory et le détruire au bon moment ?
Et si j'ai plusieurs portlets, comment peuvent-ils partager un même EntityManagerFactory ?

[natoine]

ALors je me suis dit que ça serait plus propre de faire d'un EntitiyMangerFactory un attribut de portlet.

J'ai donc déclaré l'attribut suivant :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

private static EntityManagerFactory emf = Persistence.createEntityManagerFactory("portletsAnnotation");

Et j'utilise désormais toujours le même emf.

Je build, je déploie et là, erreur, il ne trouve plus mon hibernate.cfg.xml qui est dans META-INF...
Alors je déplace ce fichier dans webapp et là, il n'arrive plus à faire le mapping des classes.
Il me sort l'erreur :
