Struts + OpenJPA + MySQL + TomCat
Bonjour,
J'ai un problème pour l'installation de openJPA.
J'ai le fichier persistence.xml (dans le répertoire META-INF) suivant :
Code:
1
2
3
4
5
6
7
8
9
10
11
12
13
| <?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:
1
2
| EntityManagerFactory emf = Persistence.createEntityManagerFactory("test");
em = emf.createEntityManager(); |
J'ai l'erreur suivante :
