Can anyone show me how to do a self-join using Annotations?

something like:

public class Person() {
private Person friend;

public Person getFriend() {
return friend;
}

public void setFriend(Person friend) {
this.friend = friend;
}
}

Any success at your end?

Code:
@Entity
public class Person() {
   @Id
   @GeneratedValue
   private Long id;
   @OneToOne
    private Person friend;

    public Person getFriend() {
        return friend;
    }

    public void setFriend(Person friend) {
        this.friend = friend;
    }


simple, isn't it?
