AJAX enables rich desktop-like user interfaces in the browser and enables interactive interfaces that can even replace traditional user interfaces. DWR (Direct Web Remoting) is an Open Source Java framework for building AJAX applications. DWR's main idea is to hide AJAX implementation details, like XMLHttpRequest, from developers. By using DWR, you can concentrate on developing the application and business objects and leave AJAX details behind the scenes where they belong. DWR allows server-side Java classes to be used in the browser and JavaScript functions to be used on the server (Reverse AJAX).
This book will show competent Java programmers how to work with DWR to create powerful AJAX applications. It starts with a tutorial on DWR's main features and functions. Then it covers setting up the development environment. Finally, it concludes with some sample applications.
The later chapters are full of example code for sample applications, to aid comprehension.
