Session interface Certain redundant methods were deprecated and removed from the org.hibernate.Session interface. However, to make migration easier, these methods are still available, via the org.hibernate.classic.Session subinterface. These deprecated methods are:
query execution methods: find(), iterate(), filter(), delete() saveOrUpdateCopy() Hibernate3 applications should use createQuery() for all query execution, DELETE queries for bulk delete and merge() instead of saveOrUpdateCopy(). Existing applications may continue to use the deprecated methods.
