This sounds like a reasonable persistence.xml (including the EclipseLink provider name) :

> version="2.0">
> <persistence-unit name="persistenceUnit" transaction-type="JTA">
> <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

Note the JPA 2.0 schema ships with the GlassFish distro (glassfish/lib/schemas/persistence_2_0.xsd)
