EclipseLink in OSGI Bundle persistence.xml not found

Question

I have a problem with EclipseLink. I am using GlassFish v3.1 and I am trying to use EclipseLink for my save level. I followed all the tutorials available on the Eclipse wiki without any success. My persistence.xml file cannot be parsed, and I get this error when trying to create an EntityManagerFactory:

org.eclipse.persistence.exceptions.PersistenceUnitLoadingException Exception Description: Fixed error when processing persistence.xml from URL: bundle: //307.1: 1 /

Here is my persistence.xml located in / WEB -INF / classes / META-INF /:

<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">

        <properties>
            <!-- Embedded MySQL Login -->

            <property name="eclipselink.jdbc.batch-writing" value="JDBC"/>

            <!-- Logging Settings -->

            <property name="eclipselink.logging.thread" value="false" />

            <property name="eclipselink.logging.exceptions" value="true" />

        </properties>
    </persistence-unit>
</persistence>

I added this line to my MANIFEST.MF file:

JPA-PersistenceUnits: generic
