Markus, you get this exception because Database(Impl) simply isn't serializable, and imho shouldn't be either.
Can you just briefly explain why you are getting this exception ? Or even better, what's the problem you are trying to solve. It looks like you are binding a Database instance (as obtained via JDO.getDatabase() to a HttpSession, correct ? If that's the case, I'd consider to change your usage of Castor, as obtaining Database instances from JDO is not expensive at all (especially when using a connection pool with Tomcat).
