What You Will Learn

  • Will make your development faster and simpler by teaching you the features of DWR and implementing it with Reverse AJAX.
  • Teaches you how to use DWR JavaScript libraries, Convertors, Creators, Filters and Signatures. Integration with other projects, and Security – factors which are essential to developing any DWR application.
  • Specifies practical aspects such as supported browser and environments, configuration, setting up development environment, testing and debugging, error handling, packaging and deployment in a comprehensive manner, by demonstration where required.
  • Provides a practical demonstration of creating a dynamic user interface, implementing tables and lists, and field completion for you to derive concepts from.
  • Shows advanced elements of user interface through practical examples of creating forms, building a navigation tree, and map scrolling.
  • Teaches back-end integration: integrating a database with DWR, integrating with web services, and integrating with a messaging system.
  • Includes collaborative book authoring and chatroom applications, which show how easy it would be to enhance your applications to production grade using these samples as a starting point for development and as a source of ideas.

In Detail

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.
