Re: [eclipselink-users] Eclipselink in SE Environment not able to provid

[Tom Ware <tom.ware@xxxxxxxxxx>]

The way Persistence works is like this:

It goes looking for persistence providers based on a service advertisement in 
the jar located in META-INF/services.   (in eclipselink.jar there is a file 
called META-INF/services/javax.persistence.spi.PersistenceProvider)

For each provider it finds, it attempts to create an EntityManagerFactory and 
returns the first one it is capable of finding.

Please set your the eclipselink.logging setting in your persistence.xml to 
FINEST and post the logging information you get when you call 
Persistence.createEntityManagerFactory()

Also, try listing your de.eclipselink.db.User as a class in your persistence.xml 
to see if it helps.
