Application Client Enity Manager cannot find Persistence Unit with Java Web Start

[dbritton]

I have an Enterprise Application Project in Netbeans 6.7.1.

The enterprise application client module has the business code and the
persistence unit (TopLink) defined in the app-client.jar. I can run this
application clinet from NB without a problem.

I'm using JPA (EnityManager) in a Java SE environment.

When I try and run the app-client from Java Web Start I get an error
that the EnityManager cannot find the PU. The persistence unit is packaged in the app.ear->app-client.jar->META-INF->persistence.xml.
There's not a wealth of information, that I could find on the net, but this
seems to be correct.

The error I get is:
INFO: ACC009: Load Application Class: [jws.Main]
hello world! From JWS
Dec 3, 2009 11:44:21 AM com.sun.enterprise.appclient.MainWithModuleSupport <init>
WARNING: ACC003: Application threw an exception.
javax.persistence.PersistenceException: No Persistence provider for EntityManager named JWS-app-clientPU: The following providers:
oracle.toplink.essentials.PersistenceProvider
oracle.toplink.essentials.ejb.cmp3.EntityManagerFactoryProvider
Returned null to createEntityManagerFactory.

Any ideas on what I need to do to properly package the PU for an Enterprise Application Client ??

Thanks,
David

Is this related to the bug below. If you are using TopLink or EclipseLink. You can not use the application client in offline mode if the persistence.xml file is retrieved from the server. Please vote on the bug.
