Hi, I was looking into as documentation as to how the code was organised like business layer and stuff. Are you implying that the architecture to the springframework petclinic and jpetstore are the same.
I suppose the answer to that depends on what you mean by architecture. The packages are laid out a bit different and each application may use different types of controllers and use different features from the spring framework. Both use a MVC pattern but each application may use a different implementation for one or more of the tiers. For example, the default persistant storage implementation for petlclinic uses Hibernate, while the implementation for JPetstore is ibatis.
As Brandon also surmised the Springframework version of JPetstore can be configured to use either Struts or Spring web MVC for the web tier.
The document you mentioned in another message on PetClinic is quite good but I'm not sure there's anything like it for JPetStore. I careful reading of the source code should provide information where the applications are different. I've been using the Springframework for a project I started about 6 months ago and essentially started using the Springframework JPetStore application as a template.
If you're looking for another sample web app to examine for an architecture that may work for your own web application you might want to take a look at Matt Raible's AppFuse. It demonstrates how to integrated several technologies including Spring, Hibernate, XDoclet, iBatis, JSTL and Struts, and Spring MVC.
