[jboss-user] [EJB 3.0] - How to save entities with PrimaryKeyJoinColumn?

Could someone give me some insight into the correct way to save entities that are joined over their primary key? I have two entities: Field and FieldAccess. They both share the same primary key and have a relation over their primary key: class Field { @OneToOne (mappedBy = "field") protected FieldAccess fieldAccess; } class FieldAccess { @OneToOne @PrimaryKeyJoinColumn(name = "fieldid", referencedColumnName = "fieldid") protected Field field; } I'm using Oracle Sequences to generate primary keys. When saving a new entity, how does the primary key get propagated from one entity to the other? I've tried the following but the primary keys never end up being the same: FieldAccess fieldAccess = new FieldAccess(); entityManager.persist(fieldAccess); Field field = new Field(); field.setFieldAccess(fieldAccess); fieldAccess.setField(field); entityManager.persist(field); What am I missing?
