Configure toplink for weblogic 10.3

Question

Hello everyone,
I am totally frustrated, please help. I have installed toplink in any path you could imagine, and configure the persistence.install as I saw in google. Could you give me a guide, for silly people, for configuring toplink into weblogic 10.3?
The problems come with the following persistence.xml, it says noclassfoundexception for oracle.toplink.essentials.PersistenceProvider:
<?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="Default" transaction-type="RESOURCE_LOCAL">
<provider>oracle.toplink.essentials.PersistenceProvider</provider>
<properties>
<property name="toplink.jdbc.driver" value="oracle.jdbc.OracleDriver"/>
<property name="toplink.jdbc.url" value="jdbc:oracle:thin:@192.168.146.18:1523:Desacap"/>
<property name="toplink.jdbc.user" value="CAP_OWN" />
<property name="toplink.jdbc.password" value="CAP_OWN" />
<property name="toplink.logging.level" value="FINEST"/>
</properties>
     </persistence-unit>
</persistence>
Thanks in advance.

WebLogic Server 10.3 ships with Apache OpenJPA and Kodo as persistence providers to my understanding. Therefore if you want to use TopLink, etc, you'll have to install the TopLink libraries somewhere in your application. APP-INF/lib, WEB-INF/lib or a shared library, etc. Can you expand on "I have installed toplink in any path you could imagine" and detail which jars you've tried to install and where you've tried to put them?
There is also a TopLink specific forum where you might find more expertise:
