Hi @Christian, I try to explain better and, if you can take a look, I have created this test case https://github.com/tomasell/hibernate-testcase/tree/inheritance
I need to create a relationship

@ManyToOne

or

@OneToMany

between two generic classes.
If you run the test, you can receive the follow error message

mappedBy reference an unknown target entity property

I suppose I cannot use this kind of relationship because hibernate cannot create foreign keys. Right?
