BookFk is an embedded class intended to be used by entities like Chapter and others. It is NOT intended to be a standalone entity or have a Primary Key. So, when I try your fix I get the following compile error:
SEVERE: Class struts2.example4.BookFk has application-identity and no objectid-class specified yet has 0 primary key fields. Unable to use SingleFieldIdentity. This pattern was submitted by Bryce as a way of better handling redundant data related to FK fields such as Chapter.book in this case.
