Ajax on Java
This practical guide shows you how to make your Java web
applications more responsive and dynamic by incorporating
new Ajaxian features, including suggestion lists,
drag-and-drop, and more. Java developers can choose between
many different ways of incorporating Ajax, from building
JavaScript into your applications "by
hand" to using the new
Google Web Toolkit (GWT).
Ajax on Java starts with an introduction to Ajax, showing
you how to write some basic applications that use
client-side JavaScript to request information from a Java
servlet and display it without doing a full page reload. It
also presents several strategies for communicating between
the client and the server, including sending raw data, and
using XML or JSON (JavaScript Object Notation) for sending
more complex collections of data.
The book then branches out into different approaches for
incorporating Ajax, which include:
The Prototype and script.aculo.us Javascript libraries, the
Dojo and Rico libraries, and DWR
Integrating Ajax into Java ServerPages (JSP) applications
Using Ajax with Struts
Integrating Ajax into Java ServerFaces (JSF) applications
Using Google's GWT, which offers a pure Java approach to
developing web applications: your client-side components are
written in Java, and compiled into HTML and JavaScript
Ajax gives web developers the ability to build applications
that are more interactive, more dynamic, more exciting and
enjoyable for your users. If you're a Java developer and
haven't tried Ajax, but would like to get started, this book
is essential. Your users will be grateful.
