Is this true for eclipse 3.7 ?
If so, could you please guide me too?

I debugged down the creation of EntityManagerFactory and EntityManager from a 
PDE-plugin and from what I saw, the plugins classloader does not even try to 
look into a library. 
If I got it right, this is explicitly disabled by resetting the plugins 
classloader internally.
Or is there a major difference between adding a library and adding a dependency 
to another plugin?

So how do I have to add the eclipselink.jar to a plugin, that all service 
loading succeeds?


kind regards
