[Data] Transaction qui ne semble pas utilisée

Bonjour,

Je commence un nouveau projet Sping/Hibernate, Spring est censé gérer mes transactions.

J'ai donc une classe UserHelper dont la méthode writeTest est rendue transactionnelle.

Mon soucis est que si je vois bien une session s'ouvrir et une transaction commencer dans les logs, celle-ci ne semble pas "visible", la moindre action sur la session provoque alors une exception.

Le plus étonnant est que si je modifier ma méthode writeTest à la main pour ouvrir une session et une transaction alors tout se passe bien (le code ci-dessous contient cette modification en commentaire).

Ce n'est pas mon premier projet Hibernate/Spring, c'est pourquoi je comprends d'autant moins mon bug... mais là je sèche depuis 2 jours ^^

Voici mes sources :
