title: Hibernate mapping, on a unmapped class
body: <p>I' ve got 2 tables... Challenge and ChallengeYear, ChallengeYear is only to create a list of years in challenge.</p>
  
  <p>I only want to make Challenge an entity, containing a list of List years. Is this possible?</p>
  
  <p>I've looked in to @SecondaryTable together with @JoinColumn and @OneToMany, but neither of those can do the trick, or i am overlooking something.</p>
  
  <p>Can someone help me?</p>
  
  <p>Greetings,
  Jan</p>
