Hi Please check your Persistence Name in your persistance.xml file and the persistence name in your EntityManagerFactory. This might be the case if your classpath does include EclipseLink already.
Ex: peristence.xml file
<? xml version="1.0" encoding="UTF-8"?>
< 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="PersistenceUnitName" transaction-type="RESOURCE_LOCAL">
< exclude-unlisted-classes>false</exclude-unlisted-classes>
</ persistence-unit>
</persistence>
EntityManagerFactory class:
entityManagerFactory = new PersistenceProvider().createEntityManagerFactory("PersistenceUnitName");
Hope this helps.
Thanks
Kris

The fact that you are not seeing any logging information likely indicates that
for some reason your run target is not seeing eclipselink.jar as a service
provider.
That could mean either your classpath is not setup properly or your
eclipselink.jar is somehow corrupt. Are you running a completely standalone
application in java, or are you running your application on some kind of
container. (Tomcat? Spring?)
It might be a good idea to do a quick debug through the persistence code. The
code is fairly simple. You can get the source here:
