The web service operates using the
http://ns.soacookbook.com/ws/catalog
namespace,
and the schema-based artifacts are defined in the
http://ns.soacookbook.com/catalog
namespace. Your build process uses XJC to generate Java objects based on the schemas before
compiling the service. The robust business logic in this example just indicates that you'll get
a book result back if you pass in “12345” as the ISBN, and an empty book otherwise.
