Name and version of the database you are using:
MySql5
So, I am not sure why it can't read the file. It doesn't give me enough information to tell me what is wrong with it. When I checked the /bin directory it managed to copy everything over from the /src directory that should be there. It just can't read the Unit.hbm.xml file for whatever reason. Maybe it can't find it (Doesn't say it can't), maybe there is a parse error there.
At first I thought it was a path problem with the file, so I have tried removing com.Game.Main. from the com.Game.Main.Unit in Unit.hbm.xml and I still get the same thing. I have copied and pasted the package name from Main.Unit into the Unit.hbml.xml file to make sure that I am using the correct package name and it still isn't reading it!
The mapping resource in the hibernate config file is...correct from the looks of it. I go in the bin directory and look there and there is the Unit.hbm.xml file in the path that was specified.
Anyways, I'm stumped.
Thanks for any help.
