One to One shared primary key association in JPA with Hibernate
One of the less commonly used mappings in JPA and Hiberate is the @OneToOne mapping with a shared primary key. Conceptually this type of mapping is simple to understand. However, recently I tried to implement this relationship between two objects and ran into some petty issues. No clear example was listed on the net, so I decided to post a solution on a blog for possible reference for others.
