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
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="eu.floranet.jpa.link"
transaction-type="RESOURCE_LOCAL">
<description>org.eclipse.persistence.jpa.PersistenceProvider,
javax.persistence.Persistence</description>
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider >

<class>
eu.link.temp.CptExposicao</class>
<exclude-unlisted-classes>false</exclude-unlisted-classes>

<properties>
<property name="eclipselink.logging.level" value="INFO"/>
<property name="eclipselink.jdbc.driver"
value="com.mysql.jdbc.Driver"/>
<property name="eclipselink.jdbc.url"
value="jdbc:mysql://server:3306/database"/>
<property name="eclipselink.jdbc.password" value="pass"/>
<property name="eclipselink.jdbc.user" value="user"/>

<property name="eclipselink.jdbc.read-connections.min" value="1"/>
<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:

Miguel,

Please ensure your persistence.xml file is located at:
META-INF/persistence.xml on your classpath. Can you also provide any
details of how your are initiating your JPA access?

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.

This is odd, the null-pointer you are seeing is occurring because the
EclipseLink class loader is null. From the java.lang.Class comment this
can only occur on some JVMs if the bootstrap loader was used to load the
class.

How are you launching your Java program, and what JVM are you using (and
what are your JVM args)?

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.
