Since this is a student project can I assume that your code is not top secret and that you have a repository for it (e.g. bitbucket)? Take a look at http://stackoverflow.com/questions/3615778/can-i-use-compositeid-on-subclasses-of-discriminated-entity-hierarchy and btw the maven dependency change that I suggested to use, please do so.
