Question

Using Hibernate how would you design and implement a search criteria page (which has multiple editable/selectable fields/drop-downs as search criteria) such that queries shouldn’t clutter data accessor code. I mean no query-string concatenation based on conditionals and ultimately all the queries should go in a separate xml file. I’ve done such an implementation using IBatis’s dynamic queries. Couldn’t find such thing in Hibernate so I started thinking what would be the elegant way to implement dynamic criteria based page in hibernate.

Sounds like you are looking for, unsurprisingly, the Criteria API:
