Thank you for pointing this out, it certainly sounds like it could be the problem, it would explain why none of the tables seem to know about one another :-D I have a singleton module which is a factory for my database connections which gets passed around into the beans, I will place these metadata and declarative base classes into that and see how that helps. I'll give this a try in the next few hours and let you know how I get on.
