Can't say much because all these classes are your application specific classes and not related to Hibernate

Hmmm.... Looked at that stacktrace again and this time found this:

Caused by: com.wamu.dashboard.util.hibernate.DashboardHibernateException: Could not instantiate dialect class



So, what value have you specified for the dialect property in your Hibernate configuration file?

Probaly using the 2.0 package structure in his dialect definition.
