[EJB3] c3p0, problème de rollback

Salut à tous,

J'utilise c3p0 comme pool de connexion pour mon projet EJB 3 avec Jboss 6 Final
et une base PostgreSQL 8.4
J'ai une entité A qui contient une liste d'entités B.
En base, j'ai une table A et une table B, B à une clef etrangere vers A.

Mon scénario : je persite mon d'entité A, dans sa liste d'entités B
j'ai un entité qui ne respecte pas une contrainte en base (table B).
Dans ce scénario le comportement souhaité est aucune sauvergarde en base
des entités A et B.

Pour ce scénario, quand j'utilise c3p0 j'ai une entité A sauvegardé en base,
quand je n'utilise pas c3p0 l'entité A n'est pas sauvegardé.

Je ne comprend pas pourquoi l'utilisation de c3p0 empeche de faire un rollback
sur la transaction ?
Dans les log de Jboss, il est indiqué pour c3p0 un mode autocommit à true,
si dans mon persistence.xml, j'ajoute <property name="hibernate.connection.autocommit" value="false"/>
c3p0 à mode autocommit à false mais je n'ai plus la possibilité de sauvegarder une entité
en base avec mon code actuel.
