What's the benefit of using this factory as a Singleton?
One of my co-students suggested making all methods static,
so you can use Factory.getXxxDAO() instead off
Factory.getInstance.getXxxDAO();
but I'm not sure about that....

The SVN version is very stable and has a few extra features (it now

Jeff,
It helps a lot, I didn't knew abator also can generate a generic DAO.
Is it recommended to use the svn version?
Thx!
