Re: [eclipselink-users] How to create EclipseLink Sessions, ORM.xml fil

[Tim Hollosy <hollosyt@xxxxxxxxx>]

Also be aware, the example on my blog uses a pure JPA approach
(mostly) the only native class I use is UnitOfWork. I think Kris is
kind of confused between the two. But just bare in mind, if you're
following my example/my code make sure you realize you're working in a
Pure JPA environment.
