[eclipselink-users] How to run EclipseLink unittests inside Eclipse?

[Patric Rufflar <patric@xxxxxxxxxxx>]

Hello,

I'd like to know how to setup eclipselink in Eclipse that I can ran  
the provided test suites or add some new.

I read:
http://wiki.eclipse.org/EclipseLink/Building#Minimum_SVN_Trunk_projects_for_JPA_or_Core_Eclipse_Development_and_Testing
and
http://wiki.eclipse.org/EclipseLink/Development/Testing/Prereq

I setup an eclipse project using the eclipselink sources which  
compiled successfully.
But when I try to ran some tests or testsuites I am getting:

javax.persistence.PersistenceException: No Persistence provider for

(or similar stack traces).

Which persistence.xml must be used? Is there some process which  
creates or moves the correct persistence.xml?
Do I have to create some tables (or run a script) in order to run the tests?

Thank you for your help and best regards,
Patric
