GAE/Datastore requires the jar "datanucleus-appengine" in the CLASSPATH (NOT "datanucleus-rdbms"), and has to have the right (old) version of DataNucleus libraries for it to work. If you use v2.1.2 of the "datanucleus-appengine" plugin, then you must use DataNucleus jars v3.1.x, following http://code.google.com/p/datanucleus-appengine/wiki/Compatibility
