Mystery solved!
The @Column annotations for the primary key fields don't go on the entity bean at all.
They go on the methods in the @IdClass only, though it doesn't break if they are in
both places.
I now know that Bill refrained from the @Column annotations for clarity of the example,
but beware of this in the book. Code below. Hope this helps someone.
