Re: [eclipselink-users] Entity name must be unique in a persistence unit 
This is a bug.
In the mean time remove the <mapping-file>META-INF/orm.xml</mapping-file> specification from your persistence.xml and please enter a bug. 

Cheers,
Guy

Subject: [eclipselink-users] Entity name must be unique in a persistence unit 



Hello again,

I added an id property in Every class.
When I configure the persistence.xml file with hibernate everything works fine. 

But when I configure it for eclipselink I get an error (see below)

Below you see a part of my persistence.xml

Persistence xml configuration
       ......
       ......
