A ASF license Struts book titled Good Practices -- Struts -- Hands on with Examples which is attached to this page. To download it (its a 3MB Word document), click the link below:
This book is current to 1.2.7, and I hope others jump in and update it to 1.3, it's a soft copy so any changes just re-upload (via attachmnets on the menu in this page) Best use is for someone teaching Struts to use this, as it has labs. I used to teach this in 30 hours 90% lab time to large groups for good rates.
Download no longer works in 1.6, help?
