I'm having some problem with EclipseLink. I'm using GlassFish v3.1 and I'm trying to use EclipseLink for my persistence layer. I followed all tutorials available on the Eclipse wiki without luck. My persistence.xml file cannot be parsed and I receive this error while trying to create the EntityManagerFactory:
org.eclipse.persistence.exceptions.PersistenceUnitLoadingException
Exception Description: An exception was thrown while processing persistence.xml from URL: bundle://307.1:1/
Here is my persistence.xml located in /WEB-INF/classes/META-INF/:

I added this line to my MANIFEST.MF:

I can now confirm that it's a bug in EclipseLink. The work around to your problem is to either get hold of EntityManagerFactory using JNDI lookup or #PersistenceUnit instead of doing Persistence.createEntityManagerFactory().
1) It looks like you are trying to use OSGi/JPA from your WAB. Correct?
2) Can you tell if you have installed any new eclipselink bundles in your system? If so, what are they?
3) Can you provide stack trace?

When i tried to deploy an application in weblogic, he give-me the follow exception:
Substituted for missing class Exception [EclipseLink-7298] (Eclipse

[class br.com.webproj.web.model.associated.pk.AssmaintainPK] is an

an embedded ID specification (attribute [AssmaintainPK] from the

I think this error occurs because the weblogic use the eclipse link, and the project an other version of jpa. But the error is in a jar included in project and i cant change and see the code. If the problem is this, what i can do to dont use the eclipse link of weblogic (obs: in JBoss the project runs normally).
I have created the OSGI bundle project with JPA 2.0 support. I am using OpenJpa as a JPA provider. when I run the bundle, I Could not create OpenJPAEntityManagerFactory. Please fine the code which I used to create OpenJPAEntityManagerFactory.

In src folder I have META-INF and i created the persistence.xml with in that(META-INF/persistennce.xml).
Please let me know to resolve this issue.
It'd probably be helpful if you listed what the error is you are getting, but it might be because you have this line twice:
<property name="openjpa.Log" value="DefaultLevel=WARN, Tool=INFO" />
This is just a stab in the dark since you don't mention what the error is and I just happen to be getting an error message of "Equivalent property keys "openjpa.Log" and "Log" are specified in configuration." for something I'm working on.
I've been searching around and haven't been able to find a working fix. My persistence.xml file is located in /src/META-INF/persistence.xml, which from looking around, this is the correct location for it.
I'm using glassfish as the server, and I keep getting the following:

Any ideas on what the problem could be would be greatly appreciated.
Hmm.. make sure you are using PeristenceUnit not context in your entity class: see http://openejb.apache.org/jpa-concepts.html
Switch to "transaction" just to see if it fails too.
Also sometimes the old classes are not unloaded from the server properly if you are doing redeployment, you may have to shut it down and restart after redeploy.
I'm trying to convert my hibernate-based GWT implementation into a JPA2 version. I've added the persistence.xml, the specific libraries and added some code just to open (by getting an entityManager). I just do a local employment, I do not use google's app engine (and I'm not intended to use it).
I get the following message:

My persistence.xml looks like:

There is no other error message, warning, stacktrace, etc.
What is wrong or in what way can I examine what the real problem is?
GAE/J doesn't do MySQL, nor JPA2 so why are you including it/specifying it in your persistence.xml? Perhaps if you post your persistence.xml then people can make an informed opinion ...
I have a hibernate project, which uses JPA.
my persistence.xml contents is as follows:
<persistence version="2.0" 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_2_0.xsd">

</properties>
</persistence-unit>
</persistence>
Now when I run it using eclipse I don't have a problem, but when I deploy it in Jboss, I get the below error:
ERROR [AbstractKernelController] Error

How can I resolve this issue?
The ClassCastException is caused by having two copies of the javax.persistence APIs in your system (one in the common classloader provided by JBoss and the one in your app). When running on JBoss, you are just not supposed to provide this API in your application, don't package it.
By the way, it seems you're using a JPA 2.0 persistence.xml but I'm not convinced you're using the JPA 2.0 implemenation of Hibernate (actually, you seem to be using a pretty old version since I can see commons-logging.jar). You should probably fix that i.e. use the 1.0 version of persistence.xml.
Actually, you should very likely use a different persistence.xml when running on JBoss (using a JTA entity manager and a jta-data-source). And it seems weird to mix data source usage and Hibernate built-in connection pool.
