[Framework] BeanCreationException ? problème d'injection de dépendances

Bonjour.

J'ai 2 projets java : TicketDao et TicketService, et un projet Grails TicketWeb.

Quand je lance le serveur Tomcat depuis Eclipse (3.4) pour démarrer TicketWeb j'ai l'erreur suivant :

Code:

1
2
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myTicketDao' defined in class path resource [services/spring-hibernate.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.TypeMismatchException: Failed to convert property value of type [org.hibernate.impl.SessionFactoryImpl] to required type [org.hibernate.SessionFactory] for property 'sessionFactory'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [org.hibernate.impl.SessionFactoryImpl] to required type [org.hibernate.SessionFactory] for property 'sessionFactory': no matching editors or conversion strategy found

voila mon arborescence :
+ TicketDAO
+ hibernate
-ITicketDao.java
-TicketDao.java (implements ITicketDao)
-Ticket.java (POJO)
-ticket.hbm.xml

+ TicketService
+ services
-Test.java
-ITicketService.java
-TicketService.java (implements ITicketService)
-spring-hibernate.xml

+ TicketWeb
+WEB-INF
-applicationContext.xml (j'import ici spring-hibernate.xml)
