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

[Leon Derks <leon.derks@xxxxxxxxxx>]

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
