I want to have a dependent object share the primary key of its parent.

I.E with tables
Table Parent
int PARENT_ID // primary key
String NAME

Table Child
int PARENT_ID // primary key, same as parent's primary key
String NAME

I read somewhere that hibernate allows the @Id annotation with a @OneToOne annotation (Is this only with a newer version of hibernate? I am running 3.2.4.sp1 (comes with jboss 4.2.3.))

So I have the following two entities:





But I get the following error from hibernate:



Any ideas? I this a hibernate problem (i.e. I need a newer version) or is there a flaw in the code?
