Problem deploying JPA project

Question

When deploying an ear containing a war with a persitence archive in its WEB-INF/lib, I get a deploy error. The error in the opmn log seems to indicate a problem with parsing some xml file, but I can't seem to find a problem with the persitence.xml. This seems to work correctly using the embedded version of OC4J included with Jdevelper but fails when deploying to a clustered App server instance on linux.
The application server version is 10.1.3.1 which matches the version of Jdev I'm using.
thanks in advance.
The persistence archive contains a persistence.xml under its META-INF with these contents
<?xml version="1.0" encoding="windows-1252" ?>
<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"
version="1.0" xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="Model" transaction-type="JTA">
<provider>oracle.toplink.essentials.PersistenceProvider</provider>
<jta-data-source>jdbc/web</jta-data-source>

Answer 1

I tried repackaging the ear. Instead of including the persistence archive in the web-inf/lib of the war, I created an EJB jar with the jpa project in it.
The application.xml now deploys that as an ejb module along with the war.
The deploy error is a little different now, it specifies a missing class, Missing class: oracle.toplink.essentials.ejb.cmp3.EntityManagerFactoryProvider.
I'm assuming that this class is in the toplink-essentials.jar. Should the toplink-essential.jar be packaged in the ear?
Again this is being deployed to a 10.1.3.1 Application server.
thanks
