DWR Java AJAX Applications

by Sami Salkosuo

AJAX enables rich, desktop-like user interfaces in the browser and as well as interactive interfaces that even replace traditional user interfaces. DWR (Direct Web Remoting) is an open source, Java framework for building AJAX applications. DWR's main contribution 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 the 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 shows competent Java programmers how to work with DWR to create powerful AJAX applications. Starting with a tutorial on DWR's main features and functions, it then covers setting up the development environment. Finally, it concludes with some sample applications.

The later chapters are full of example code for sample applications.
