Where to save the hibernate.cfg.xml ?

hibernate.cfg.xml must be found in the root of the classpath when the webapp is started.

If you are using maven to build the project, put hibernate.cfg.xml in the src/main/resources directory so that when you build the war package, it will be automatically be placed in /WEB-INF/classes

If not using maven, place the file directly in your WEB-INF/classes dir
