Presentation layer
WebSphere Commerce uses Java Server Pages (JSP) to implement the view layer of the Model-View-Controller (MVC) design pattern.

Userdata changes in support of command extension
There are two types of extensions that are supported with Business Object Documents (BODs) in the IBM Sales Center, that do not require a change to the BOD schema definitions.

By default, the create and sync Business Object Documents will map the name value pairs in the Userdata element to the request properties of the mapped controller command. For get BOD messages, you can add new search criteria to the ReturnCriteria element.
