FYI, I've split out the ScalaEntityManager stuff into its own project: http://scala-tools.org/mvnsites-snapshots/scalajpa/
Snapshot version right now mostly because I haven't had time to really test it and I haven't heard of anyone using it yet. Hopefully this will further simplify things for people using JPA. Right now most of my time is taken up working on the book, but once that's done I'll devote more time to improving JPA support in Scala and Lift. In the meantime, please let me know if you run into any issues. Derek On Mon, Mar 2, 2009 at 7:03 PM, Meredith Gregory <[email protected]>wrote: > Josh, > > Brilliant!
