title: Hibernate aggregating
body: <p>Is it possible to get as a result from hibernate directly this...</p>
  
  <pre><code>List&lt;Map&lt;Sth, List&lt;SthLog&gt; list;
  </code></pre>
  
  <p>when classes are mapped in such a way (not bidirectional)?:</p>
  
  <pre><code>@Entity
  public class SthLog {
  
          @ManyToOne(fetch=FetchType.LAZY, cascade=CascadeType.ALL)
      private Sth sth; }
  </code></pre>
  
  <p>I know that this maybe seems to be a silly question, because normally you can add bidirectional mapping, but in this case I can change entities definition and I wonder if I can get required structure directly from hibernate.</p>
