A sample chapter from our upcoming book is now available here. It covers DynaForms and the Struts Validator Framwork. It is both a very handy reference to a fairly new technology, and a good sample of what you can expect to see if you go buy the whole thing.
Remember, it's never too early to pre-buy the book on Amazon! They make great stock stuffers. Hours of fun for the whole family. Batteries not included. Some assembly required. Not appropriate for those under the age of 7.
