I am having great difficulty in getting a one-to-one primary key association to work. I have read section 5.1.11 in the Hibernate Reference Manual and also chapter 6 in the Hibernate in Action book to no avail. In section 5.1.11 they give an example of a one-to-one primary key association, but they only list the partial mapping snippets. Does anyone have the full mapping files and corresponding Java classes? I believe this would help me to figure out what I am doing wrong.

Hibernate version: 2.1.7
