Hello, I've used hibernate tools to reverse engineer an oracle 10g database. It has generated java classes for every tables as expected, but when i try launch my program, i get a Duplicate Mapping Exception. There is a single, generated, hbm.xml file for each classes and there are no annotations. What could the problem be?
