Die einzige Möglichkeit, die ich kenne, um via Criteria zu gruppieren ist:

Code:
List<Person> result = statelessSession.createCriteria(Person.class)
            .setProjection(Projections.groupProperty("name"))
            .list();


das bedeutet allerdings auch eine automatische Projektion auf das Attribut 'name'. Wenn ich nun aber eine Liste mit Objekten zurückgeliefert bekommen möchte, analog zu:

Code:
select * from Person group by name


wie mache ich das?
