The above is the answer from Gavin ;) To get a more complete list we simply just need to go through the thirdparty-all.jar and figure out what is in there precisly; I could do that, but you could do it too (hint hint ;) If you generate the list then I can verify it for you. I think that will be the most efficient way of doing it. Simply look at the packages in the .jar and find the corresponding one in hibernate3/lib.
