A
- @Id int id
- String aName
- String bName - FK not working

B
- @Id int id
- String bName - unique


Can FK reference only to @Id?
How to make this work?

Hi I'm not sure I understand the problem but here something I tried:

class Person : http://pastebin.com/HR9H8atv
is containing a OneToOne relationship with a PersonBiography : http://pastebin.com/CCZiwNaf

That PersonBiography has it's own @Id but the OneToOne is linked by a String name attribute

With a persistence.xml like this: http://pastebin.com/PrZV2T0H

I think it gives what you where trying to do...

Thank you for response ecor6633, problem solved and was different. For future reference and google search:

Was using Spring Data JPA, OneToMany mappedBy column that you reference to in a foreign @Entity has to be defined as @Column with actual name.
Without reference FK you don't have to put @Column because it will be converted to @Column automatically.
