This is more a Hibernate than GWT issue. From your error log, it looks like it boils down to you not configuring it correctly. If you look at the newer Hibernate, there's no XML configuration. It's all done through annotations, which are a lot easier to understand.
You may want to look into just getting hibernate running on its own in a standalone java application, and then just adding a GWT RPC glue layer around it if you are indeed planning on doing some kind of web-app stuff.
