[Data] Problème de Transaction

Bonjour !

Je commence depuis peu Spring et je dois dire que là je bloque!
J'ai suivi le tutoriel disponible à cette url : http://baptiste-meurant.developpez.c...ing-hibernate/

Non sans modifier un peu le nom des classes pour que ça colle avec ma table.
Je souhaite simplement faire un formulaire html qui me permette de définir si le couple login/password est correct et si oui mettre en session l'utilisateur.

J'ai donc ces fichiers :

ApplicationContextDao.xml

Lors de l'appel à la méthode getCurrentSession(); il m'envoie une jolie Exception de ce genre...

Code:

Caused by: org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here
	at org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63)
	at org.hibernate.impl.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:622)
	at com.ww.dao.hibernate3.AccesDaoImpl.checkLogin(AccesDaoImpl.java:21)
	at com.ww.service.impl.AccesManagerImpl.checkLogin(AccesManagerImpl.java:29)
	at com.ww.servlet.UserServlet.checkLogin(UserServlet.java:99)
	... 20 more

J'ai donc regardé de plus près ce que me renvoyait getSessionFactory() et une chose me choque... c'est que le membre transactionManager est null alors que je l'ai définit dans ApplicationContextDao.xml.

Qqun saurait m'aiguiller pour résoudre ce problème ?

Merci :D
