I have 2 entities :Customer & Address.

With @OneToOne and @JoinTable Customer.java looks like this:



Now Address.java



When I try to persist a customer I get the following stack-trace:



I have tried this change in Address entity:



with no effect. Surely this could be done without using JoinTable.But I want to do it this way for academic interest.Is it possibe?

I assume that this design is part of a learning experience. However, if this is a production design then you should ask yourself, Does an address really need to point back to its owner?

Thanks Ron.
You are correct that this is part of a learning experience.There is no need for address to point back to customer.Let's say there are 2 entities A & B which have a bi-directional association. In that case I think shared primary key will be the preferred technique.
