Bonjour,

Je développe une applciation Spring MVC/Hibernate/Mysql

Au démarrage de Tomcat j'ai cette erreur :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]: Cannot resolve reference to bean 'idDataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'idDataSource' defined in ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]: Instantiation of bean failed; nested exception is java.lang.IllegalStateException: No bean class specified on bean definition

Il ne trouve pas le bean référencé idDataSource, mais j'ai pourtant bien défini idDataSource comme bean (cf code ci dessous).
Savez vous pourquoi j'ai cette erreur?
Merci d'avance.
