[jboss-user] [EJB 3.0] - entity question

Is it possible to use Interfaces for OneToOne relations?

For example (Pseudocode):

  | Entity A implements MarkerInterface {}
  | Entity B implements MarkerInterface {}
  | Entity C {
  |  MarkerInterface something;
  | }

I know that its possible to use Inheritance, but im unable to use the same BaseClass in A and B.

I just want to avoid this:

  | Entity class C {
  |  A a;
  |  B b;
  | }
Where its only allowed to set a or b instead.

thx for your help,
