You should rather have a look at Simple PetStore, a rewrite of the PetStore with simple tools and frameworks (Simpleframework, JDBC, Buildr, no IoC container).
I don't plan to make significant changes to this version anymore.
A sample Java web application to demonstrate applying the principles and practices described in Steve Freeman and Nat Pryce book, Growing Object Oriented Software, Guided by Tests.
This version is built on top of:
- Spring MVC 3.0
- Spring Core 3.0
- Hibernate 3.5
- Velocity 1.6
- Sitemesh 2
- Bean Validation API 1.0
- Maven 2/3.
See the wiki for information on building and starting the application.
