Answer 2

A more flexible solution may be:

criteria.setProjection(Projections.distinct(Projections.property("property")));

Answer 3

depends on your query/criteria. if you provide a unique id you can call criteria.uniqueResult() otherwise you call criteria.setMaxResults(1) and call criteria.uniqueResult()
