Configuration datasource Spring + jpa + hibernate

Bonjour,

Ca fait plusieurs jours que j'essaie de configurer mon accès aux données via spring.
J'utilise la version 3.2.0 avec hibernate 4.0.1, java6 et tomcat 7.

Mon fichier applicationContext.xml :

Persistence.xml

Code:

1

3
4
5
6
7
8

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">

            <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle9Dialect"/>
            </properties>
	</persistence-unit>
</persistence>

Dans mon code Java, j'essaie de récupérer l'entityManager comme ceci:

Code:

1
2
3
4

6
 
@PersistenceContext
private EntityManager testem;
public void setTestem(EntityManager testem) {
	this.testem = testem;
}

Mais l'entityManager est toujours null. Idem avec le unitName="myApp" défini.

Une idée?

Merci d'avance.
