A standalone sample application called Bugzooky is included in Stripes. Browsing the source code and JSPs for the application is one of the best ways to get to grips with some of the more advanced features of Stripes.

The Bugzooky sample application has examples of how to use the following features (among others):

Indexed properties (aka multi-row forms)
File upload
Streaming data back to the client for download
Built in and custom validation
Multiple events from a single form
Re-using the same pages and ActionBeans for add flows and edit flows

A few screen shots and an example class and JSP follow to whet your appetite.
