you are missing hibernate.jar with MappingException in it.

in hibernate2 the class MappingException is located in this package:

\net\sf\hibernate\MappingException

otherwise in hibernate3 the class MappingException is located in this package:

\org\hibernate\MappingException

I due to new version of hbm2java for hibernate 3.

Bye
