Bonjour,

Je suis en train d'essayer d'implémenter Hibernate dans sur un projet tournant sous JBoss 4.0.5.
Après avoir pas mal tâtonner, j'ai réussi à utiliser Hibernate via des fichiers hbm, puis avec des annotations, mais je bloque sur le EntityManager.

Voici les infos que je peux fournir (je ne sais pas si tout est utile) :

persistence.xml :

Code :

A noter qu'il n'y a que lorsque j'appelle le commit que l'insertion en base se fait, malgré l'exception générée.
Je crois comprendre que c'est JBoss qui devrait gérer la transaction (et donc le commit) ? Sauf que je ne voie pas comment lui dire...

Cordialement.

Après d'autres tests, j'ai remarqué que si je défini la connexion à la base dans le fichier persistence.xml au lieu d'y faire appel au fichier mysql-ds.xml de JBoss, je n'ai plus d'erreur.
Mais je suppose que le comportement de la persistance n'est alors plus le même non plus.

J'ai trouvé la solution en apportant des modifications au persistence.xml :

Du coup, dans mon DAO, plus besoin de faire appel à em.getTransaction(). Un simple em.persist(objet) suffit.
