Hi Bert:
It looks like a table game :-)
Well you went to the next step and you are faced with the next trivia :-D
AFAIK, the problem is that you need to JDO "enhance" your classes. See the
build.xml that Druid did for you. Also remeber you need to use jdo 1.01
NOT jdo 1.00
Best Regards,
Antonio Gallardo
