From the GoogleCode site:
Apache Struts 2 from Square One is a training course designed for people who want to create Java web applications, not just quickly, but correctly. Training sessions include a technology primer and a coding exercise. This Project hosts materials used by the course including slide presentations, coding exercises, and a companion text book. The course can be used for independant study or in a classroom setting.As mentioned, the course is something Ted Husted developed over the years for Struts 1, and then adapted for WebWork 2, and now for Struts 2. The course itself is the usual "slides and labs" affair.
Apache Struts 2 from Square One is a textbook adaptation of the course. We'd like to print the text through LuLu.com and include it as part of the course. If people want to use the textbook for individual homestudy, that's fine too. Eventually, what we started at the Struts University site will be migrated to the Square One GoogleCode site.
With Struts 2 in GA mode, we'll have a bit more time to work on this, but there's no telling how long it will take to finish the other three parts.
In the meantime, an early release of the manuscript is available as a PDF. Enjoy!
