Hi tanilo, I've started developing a Shiro Realm to be used over GAE's Datastore low-level API (not JDO nor JPA), but have only implemented the authentication code so far. If you want, you can take a look at http://code.google.com/p/shiro-gae/
There's even a sample written with Gaelyk: http://code.google.com/p/shiro-gae/source/checkout?repo=gaelyk-test Let me know if this helps you or if you have any questions. Regards, Deluan.
