A project to use the DataNucleus JDO persistence library from Scala.
Currently, the project just defines a DataStore class that allows
you to fetch a ThreadLocal PersistenceManager. A
ScalaPersistenceManager is defined, which provides for creation
of typesafe queries that return Scala types.
Unfortunately, the best way to handle Scala collections at the moment is to define them as private Java collections and then convert back and forth to Scala collections as items are fetched from and committed back to the database. One of the major goals for the project is to provide plug-in support for Scala collections and other common Scala types, but this requires some modification of the underlying DataNucleus code.
