Edit Question
Title
Body
The following doesn't work: @Entity class Owner { @OneToMany(mappedBy="owner", cascade = {CascadeType.ALL}) protected Set<B> getBSet() { .. } } @Entity @Inheritance(strategy=InheritanceType.JOINED) class A { @ManyToOne public Owner getOwner() { ... } } @Entity class B extends A { } It causes an exception as such: org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: B.user in Owner. I am trying to avoid copying the "owner" property into class B (which will consequently "denormalize" and copy the owner key into both tables generated for entity A and B). Also, I would really like to have A and B in a separate table and not have to use a discriminator by using SingleTable inheritance. Also, I can't figure out how to do something similar by using @OneToOne between A and B (and not having B extend A).
