Sri
Sri,
May be. The instructions are written for 10.3.2.0 and
10.3.3.0 (I have worked with WLS back to 10.3.0 in 2007 but
not an earlier 10.0 version using a JPA 1.0 application).
If there is a way you could try on a later server version
- ideally 10.3.3.0 this may help.

All the steps (the manifest as well as the
prefer-application-packages element) in alternative #3 must be
done in order to override the modules jars with the ones in
your EAR/APP-INF/lib
thank you

Thanks for the response. I have seen your previous
posts on this topic and followed the instructions you have
cited (for application managed JPA 2.0).
Yet I am having this problem. Could it have to do
with the fact that I am on WebLogic server 10.0? Are the
instructions different for it?
Sri
Sri,
I have this one. Reproducing on 10.3.3.0 - done,
reverifying CM and AM workarounds - in progress.
I will get back to you shortly on this forum.
In short for WLS 10.3.3.0 and WLS 10.3.2.0 only:
1) For an application managed JPA 2.0 persistence unit -
follow the instructions to override everything on the server
using your EAR (no server modifications)
http://wiki.eclipse.org/EclipseLink/Development/JPA_2.0/weblogic#DI_1.1:_Alternative_3:_Application_Level_Shared_Library_-_In_Use
2) For a container managed JPA 2.0 persistence unit - follow
the section that essentially places the JPA 2.0 spec jar above
the server-required JPA 1.0 jar (server modifications)
http://wiki.eclipse.org/EclipseLink/Development/JPA_2.0/weblogic#DI_1.1:_Alternative_2:_Reference_higher_in_the_server_classpath_via_commEnv.cmd
I will advise when the following...
Caused By: weblogic.deployment.EnvironmentException: Error
loading the persistence descriptor META-INF/persistence.xml
from the module
org.eclipse.persistence.example.jpa.dataparallel.serviceEJB.jar.
See the following stack trace for nested errors:
weblogic.descriptor.DescriptorException: VALIDATION PROBLEMS

C:\wse\wls10330\org.eclipse.persistence.example.jpa.dataparallel.serviceEJB\build\classes\META-INF\persistence.xml:2:3:2:3:

I am having no luck deploying my application that
uses JPA 2.0 API to a WebLogic 10 instance.
The application is deployed as an EAR as
explained
in the Eclipselink wiki. The error I see at startup
suggests that WebLogic is continuing to use its (internal)
JPA 1.0. The error is:
at
weblogic.descriptor.internal.MarshallerFactory$1.evaluateResults(MarshallerFactory.java:234)
at
weblogic.descriptor.internal.MarshallerFactory$1.evaluateResults(MarshallerFactory.java:221)
at
weblogic.descriptor.internal.MarshallerFactory$1.createDescriptor(MarshallerFactory.java:146)
It is almost as if WebLogic is ignoring JARs in the
APP-INF/lib directory of the EAR.
If I were to downgrade my persistence.xml to version
1.0, the above error is replaced by a ClassCastException

I realize that this is not an Eclipselink problem per
se. I am writing in the hope that al fellow subscriber to
this list has encountered this problem and has a
workaround. I have
posted this issue to Oracle’s WebLogic forum as
well.
