To update this thread, the way I got this working when building the
project in Netbeans 7.2 was to add OpenJPA as a persistence provider by
using the jar files contained in the OpenJPA bin release. Netbeans then
automatically adds the correct <provider> entry in the persistence.xml
file for OpenJPA. Under additional compiler options in the project
settings I added -Aopenjpa.metamodel=true
The meta classes were then compiled to
<project-home>/build/generated-sources/ap-source-output and were
included in the /dist war file for deployment.

Did you generate jpa meta classes?

I'm having trouble making TomEE happy on my deployed server and I'm not
sure what is different from my dev environment. Basically I have my EJB
class files included in a jar in the lib folder of TomEE as well as in my
deployed WAR web app.
When EJBs are invoked, I get exceptions like:
ClassCastException: cannot convert class A to class A.
I also get exceptions about duplicate NamedQuery's.
So I assume duplicate instances of class files present and TomEE is not
able to sort this out for some reason. So if I remove the EJB classes
contained in the /lib folder jar of my class files, I get:
WARNING: Meta class "com.company.entities.**Customer_" for entity class
com.company.entities.Customer can not be registered with following
exception "java.security.**PrivilegedActionException:
java.lang.**ClassNotFoundException:
com.company.entities.Customer_**"

Any advice regarding what I might be doing wrong ? 2-1 seems to equal 0
here :-)
