Transactions et EJB

Salut,

J'ai un problème de transaction avec mes EJB et je suis vraiment bloqué.

J'ai un EJB Entité Utilisateur, un EJB Entité Compte, tous les 2 mappés correctement, sachant qu'un Utilisateur peut avoir un ou plusieurs "Compte".

J'ai un EJB Session UtilisateurBean :

Code:

@Stateful
@Name("utilisateurBean")
@Scope(ScopeType.SESSION)
public class UtilisateurBean implements IUtilisateur {
 
	@In
	@Out(scope=ScopeType.SESSION,required=true)
	EiUtilisateur eiUtilisateur;
 
	@PersistenceContext
	EntityManager em;
 
	@Logger
	private static Log log;
 
	@Begin(join=true)
	public void begin()
	{
		log.info("begin");
	}
 
	/**
         * Ajoute un utilisateur
         */
	public String add()
	{
		log.info("add user");
		try
		{
			em.persist(eiUtilisateur);
		}catch (Exception e) {
			log.info(e);
		}
		return "/newaccount.xhtml";
	}
 
 
	@Destroy @Remove
	public void destroy()
	{
		log.info("destroy UtilisateurBean");
	}
 
}

Sur une page JSF, je créé un Utilisateur, pour ça j'appelle la méthode Add, l'ajout dans la base s'effectue correctement, je le vois dans le Log de la Console, je suis redirigé vers une autre page JSF pour la création d'un Compte.
Là je fais appel à mon 2ème EJB Session CompteBean :

Code:

1

@Stateful
@Name("compteBean")
@Scope(ScopeType.SESSION)
public class CompteBean implements ICompte {
 
	@In(required=false)
	@Out(required=false)
	private Compte eiCompte;
 
	@In(scope=ScopeType.SESSION, required=true)
	private Utilisateur eiUtilisateur;
 
	@PersistenceContext
	private EntityManager em;
 
	@Logger
	private static Log log;
 
 
	/**
         * Créé un compte temporaire lors
         * de la création d'un nouvel utilisateur
         */
	public String createTempCompte()
	{
		log.info("createTempCompte");
 
		try
		{
			eiCompte.setUtilisateur(eiUtilisateur);	
			em.persist(eiCompte);
		}catch(Exception e)
		{
			log.info(e);
		}
		return null;
	}
 
	@Destroy @Remove
	public void destroy()
	{
		log.info("destroy compteBean");
	}
}

Et lorsque sur cette page j'appelle la méthode createTempCompte, voilà le message d'erreur que j'obtiens :

J'ai essayé de flusher manuellement dans UtilisateurBean, mais ça n'a aucune conséquence. Je travaille comme vous l'aurez peut être remarqué avec JBoss Seam.
