If you're not using Google App Engine (and I'm not sure why you would
be if you're using Mysql as your datastore), then remove it from your
project's setup.  The enhanced Security Manager settings that comes w/
using GAE is what's causing your error.

Right click on you project's icon, choose Google-> App Engine
Settings..., then uncheck the "Use Google App Engine" box.
