Bonjour,

je tente de faire une application avec spring / hibernate (je ne souhaite pas mettre JPA pour la partie DAO afin de profiter des petits plus d'hibernate).

Côté Spring, j'utilise le fichier context.xml suivant:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

        <property name="sessionFactory" ref="sessionFactory" />

</beans>

côté hibernate j'utilise le fichier de configuration suivant:

Quand je tente de créer mon context spring j'obtiens l'erreur suivante:

tu n'aurais pas oublié la déclaration de la DataSource.
