I humbly disagree with J.Hughes who gave it two stars but stated it should only receive one star. The book had a rudimentary intro to AJAX because the author believes (as do I) that the term "AJAX" has been applied to many things. One must define the domain within which one works. The author did this, framing each technology well. The author gives you a good introduction into the AJAX frameworks that the reader could explore.The reason for the second half of the book is to introduce the reader to how DWR would fit in various scenarios. The author explored several other AJAX technologies to accomplish this. This will demonstrate to the average reader how to incorporate whatever framework they are using, into the DWR way of doing things. The book was far from comic relief and I'm not sure why that is a bad thing in our dry subject matter industry (i.e. programming).I believe this is not for the J. Hughes of this world who hate the presentation of subject matter within actual working programs. Yes you can drop the WAR file into the Tomcat webapps directory and poof you're see the application running. I liked the format, it help me learn many things. I am a tinkerer, and the best way to use ALL of the code that came from the author is to take bits and pieces from a program and get it working for yourself. Like the Dwiki example, I took the Login form and wanted to just make that work. The author also gives you additional project ideas to take the DWiki (or any of the other projects) further. I think this is a good format for the learner.Being an avid reader, I believe the J.Hughes type of person wants a dry terse reference. Nothing wrong with that, I have several books like that, and when I'm pressed for time, and "just have to solve the problem" then this book would drive me nuts. However, I wanted to learn the WHY of DWR as well as the HOW. So this book more than satisfied that requirement.Good luck to you all. The book was well worth the money.-T-
