Hi there to everyone,
i start a eclipselink study but i get this issue all the times.
In my classpath i got a user librarie with
(eclipselink.jar,javax.persistence_1.0.0.0.jar,
mysql-connector-java-5.1.6). I configure my persistence.xml like this:
<persistence version="1.0"
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

javax.persistence.Persistence</description>

<property name="eclipselink.jdbc.write-connections.min" value="1"/>
<property name="eclipselink.target-database" value="MySql"/>
</properties>
</persistence-unit>
</persistence>
And got this error in console:

Hi Doug,
the persistence file is located at META-INF and the file contain this code:
package eu.flora.temp;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
public class MainP {
private EntityManagerFactory emf;
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
MainP p = new MainP();
p.start();
}
private EntityManagerFactory createEMF() {
try {
return Persistence.createEntityManagerFactory("PLink");
} catch (RuntimeException e) {
System.out.println("Persistence.createEMF FAILED: "
+ e.getMessage());
e.printStackTrace();
throw e;
}
}
public void start(){
this.emf = this.createEMF();
EntityManager em = this.emf.createEntityManager();
CptEntidades c = em.find(CptEntidades.class, 1);
System.out.println("Name: " + c.getEntidadeNome());
em.close();
}
}

After analyse the eclipselink.jar and read some articles i applied the
osgi bundles and after that everything works fine. I've just create a
USER_LIBRARIE with the jars bundled by osgi and change the provider in
the persistence.xml by org.eclipse.persistence.jpa.PersistenceProvider.

I use jdk1.6.0_03 and launch from eclipse with default args, and you
where right about the null-pointer. The fact of using a user librarie in
eclipse the class's aren't load and occur the class loader null. I just
link the jars in jlib of eclipselink (not using USER_LIBRARIE) and
voilâ.... Working.
THanks,
