FYI...

I've made several improvements to the PetStore application to highlight features.
  • Now uses JPA and serializers/parses JPA beans directly.
  • Ability to upload photos to highlight custom serializers and parsers.
  • Ability to perform SQL queries through a simple "workbench" API. 
The documentation has been rewritten to reflect the new application:
