HibernateDaoSupport Code but unfortunately it doesn't
work and it throws a QueryException with this message:

"query must begin with select or from...."


So I think that the problem is related to Spring usage
of Hibernate and for this reason I want to ask you to
tell me whether you tested bulk update by using Spring
Hibernate 3 dao support
org.springframework.orm.hibernate3.support.HibernateDaoSupport

class?
