Apache Wicket Cookbook
by Igor VaynbergThis is a hands-on practical guide to a large variety of topics and use cases. This book tries to use real-world examples when possible, but is not afraid to come up with a contrived pretext if it makes explaining the problem simpler. Unlike a lot of other books, this one does not try to maintain a continuous theme from chapter to chapter, such as demonstrating solutions on the same fictional application; doing so would be almost impossible given the wide variety of recipes presented here. Instead, this book concentrates on focused problems users are likely to encounter and shows clear solutions in a step-by-step manner. This book tries to teach by example and is not afraid to show a lot of code because, after all, it is for coders. This book is for current users of the Apache Wicket framework; it is not an introduction to Wicket that will bore you with tons of theory. You are expected to have built or maintained a simple Wicket application in the past and to be looking to learn new and better ways of using Wicket. If you are ready to take your Wicket skills to the next level this book is for you.

Apollo for Adobe Flex Developers Pocket Guide: A Developer's Reference for Apollo's Alpha Release (Pocket Reference (O'Reilly))
by Mike Chambers Rob Dixon Jeff SwartzWritten by members of the Apollo product team, this is the official guide to the Alpha release of Adobe Apollo, the new cross platform desktop runtime from Adobe Labs.Apollo for Adobe Flex Developers Pocket Guide explains how to build and deploy Flash-based Rich Internet Applications (RIAs) to the desktop using Adobe's Flex framework. This book describes concisely how Apollo works, and offers numerous examples for those who want to start building RIAs for the desktop right away.Why put RIAs on the desktop?
