I found this book hugely disappointing. While this book does contain useful information it is nothing that can't be found easily in free tutorials and forum posts. If all you are looking to do is put a simple EXT widget on a page and you can't seem to figure out how to use Google to garner the instructions... then this book is for you. However, if you are in search of solid explanation on how to build a dynamic and functional Rich Internet Application (RIA) then you have come to the wrong place.

I just start with ExtJS and I think this book is perfect for those like me who wants to know what can be done with this framework and get good and simple code examples.

This book is good at teaching the basics to get you up and running quickly. In my project, I found myself needing something a bit more advanced for what I was trying to do. My project is requiring the use of DWR and this book does not cover anything related to the DwrProxy. This book also covers the 2.0 version and my project requires the use of 3.0. I also found myself referencing the ExtJs extension project for what I needed to do. I did find some areas where the 2.0 version would not work in 3.0. I would love to see a cook book for ExtJs and J2EE.

This book is really very difficult to follow along with. There are some critical errors in the code download that prevents recreating the examples. Additionally in many cases in the book, the code snippets are so incomplete that following along is impossible. Chapters 8-11 are especially poorly supplied with code that is intentionally poor and with no explanation about how to customize it to work. Finally the solutions for using a coldfusion server are plainly poor advice that leads to slower loading pages. I don't know if this is because the book is out dated, as it only covers EXT JS 2.x or if it is sloppy editing. In any case, I recommend the online documentation over this book. Also EXT JS with Gears is an excellent book that is more up to date on the topic.
