Bonjour,

J'ai un problème pour l'installation de openJPA.

J'ai le fichier persistence.xml (dans le répertoire META-INF) suivant :

Code xml :

Sélectionner tout - Visualiser dans une fenêtre à part

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0">
    <persistence-unit name="test" transaction-type="RESOURCE_LOCAL">
	    <class>ejb.User</class>
        <properties>
            <property name="openjpa.ConnectionDriverName" value="com.mysql.jdbc.Driver"/>
            <property name="openjpa.ConnectionURL" value="jdbc:mysql://localhost:8081"/>
            <property name="openjpa.ConnectionUserName" value="root"/>
            <property name="openjpa.ConnectionPassword" value="root"/>
            <property name="openjpa.jdbc.SynchronizeMappings" value="webproject"/>
        </properties>
    </persistence-unit>
</persistence>

J'ai ajouté dans le répertoire "lib" les librairie JPA et le connecteur JDBC pour mySQL :
openjpa-all-2.0.0-EA2-SNAPSHOT.jar
mysql-connector-java-5.1.7-bin.jar

Lorsque j'exécute le code suivant :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

EntityManagerFactory emf = Persistence.createEntityManagerFactory("test");
em = emf.createEntityManager();

J'ai l'erreur suivante :

Personne n'a déjà eu le même problème que moi ?

[gadufr]

En fait il faut que le répertoire "META-INF" qui contient mon persistance.xml soit dans un répertoire source JAVA et non dans le répertoire "WebContent"

:-D
