Un composant nommé "XXX" est déjà défini dans ce module dans JBoss 7.1.1

Je n'ai pas créé le nom du haricot avec TimerServiceDispatcher dans ma demande. Mais, le JBoss jeter l'exception en raison de TimerServiceDispatcher est déjà défini dans ce module. Je ne sais pas quel est le problème. Ce que je suis absent? Ce que je dois faire?

ma demande utilise les couches 2.3, 3.0 et JPA 2.0. Je n'utilise pas EJB.
