This is pseudo class hieracy

@Entity
@Inheritance(strategy = InheritanceType.JOINED)
Mammal
{
@ManyToOne
Person owner;
}
@Entity
Cat extends Mammal

Person{
@Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
	@OneToMany(cascade = { CascadeType.PERSIST, CascadeType.MERGE,
			CascadeType.REMOVE }, mappedBy = "owner")
	private List<Cat> cats = new ArrayList<Cat>();

}

it gives the error mission property:
 javax.persistence.PersistenceException: org.hibernate.AnnotationException: mappedBy reference an unknown target entity property:
Cat.owner in Person.cats

I can confirm that the same example does work when using OpenJPA as a provider. Please see attached project for reference.


Please do not hesitate me if you have questions.
