Problème configuration datasource hibernate
Bonjour à tous,
Je suis en train de découvrir Spring et comme premier exercice j'essaye de simplement configurer une Datasource. J'utilise Spring 3.0.5, commons DBCP 1.3, Tomcat 6.0, Java 1.5, Hibernate et une base de données PostgreSQL. Voici mon fichier spring-context.xml:

Le problème que je rencontre c'est que quand je génère mon contexte Spring j'obtiens cette erreur:

Bon, l'erreur est "claire", LocalContainerEntityManagerFactoryBean s'attend à recevoir une instance de "javax.persistence.EntityManagerFactory" au lieu de "org.apache.commons.dbcp.BasicDataSource" pour son attribut dataSource. Mais quelle classe dois-je alors utiliser dans mon bean datasource? Ce que je ne comprend pas c'est que c'est ce genre de configuration que je trouve partout sur le net et personne ne semble renconter ce problème...
Si quelqu'un pouvait éclairer ma lanterne ce serait sympa !
Merci d'avance !
