This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
It's not quite that simple. There is a Hibernate Plugin that you must compile and use. Sadly, the documentation for this is horrible, so you will be left with a lot more questions.

There are many more JDO fans here.
