The page-reload cycle presents one of the biggest usability obstacles in Web application development and is a serious challenge for Java™ developers. In this series, author Philip McCarthy introduces a groundbreaking approach to creating dynamic Web application experiences. Ajax (Asynchronous JavaScript and XML) is a programming technique that lets you combine Java technologies, XML, and JavaScript for Java-based Web applications that break the page-reload paradigm.

The Yahoo! User Interface (YUI) Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, DHTML and AJAX. The YUI Library also includes several core CSS resources. All components in the YUI Library have been released as open source under a BSD license and are free for all uses.
More tools...
While writing this blog a small library of reusable components based on YUI has been started. The library was namespaced YAHOO.ext (short for Yahoo! UI extensions), and already has a few very useful classes that make day to day development with YUI much easier. All of the classes are well-documented and there are some examples of using them found in the posts on this blog. The code is of course free and has the same unrestrictive (BSD) license as Yahoo! UI.

The Tacos library project provides components and ajax behaviour for the Tapestry java web application framework. Most of the functionality is based on the exceptional dojo javascript library. Thanks dojo!
It's intent is to provide a library of high quality components that may be used in your tapestry application, as well as provide a core infrastructure for using ajax related logic in these and your own components and pages.
Site with tutorials on xmlhttprequest, drag and drop, forms, uploaders, image gallery, live search, and tabbed pages.
A must page.
This list is how I imagine sorting posts in a project. Beautiful and simple.
CGI::Ajax is an object-oriented module that provides a unique mechanism for using perl code asynchronously from javascript- enhanced HTML pages. CGI::Ajax unburdens the user from having to write extensive javascript, except for associating an exported method with a document-defined event (such as onClick, onKeyUp, etc). CGI::Ajax also mixes well with HTML containing more complex javascript.
CGI::Ajax supports methods that return single results or multiple results to the web page, and supports returning values to multiple DIV elements on the HTML page.
Using CGI::Ajax, the URL for the HTTP GET/POST request is automatically generated based on HTML layout and events, and the page is then dynamically updated with the output from the perl function. Additionally, CGI::Ajax supports mapping URL's to a CGI::Ajax function name, so you can separate your code processing over multiple scripts.
Other than using the Class::Accessor module to generate CGI::Ajax' accessor methods, CGI::Ajax is completely self-contained - it does not require you to install a larger package or a full Content Management System, etc.
We have added support for other CGI handler/decoder modules, like the CGI::Simple manpage or the CGI::Minimal manpage, but we can't test these since we run mod_perl2 only here. CGI::Ajax checks to see if a header() method is available to the CGI object, and then uses it. If method() isn't available, it creates it's own minimal header.
A primary goal of CGI::Ajax is to keep the module streamlined and maximally flexible. We are trying to keep the generated javascript code to a minimum, but still provide users with a variety of methods for deploying CGI::Ajax. And VERY little user javascript.
Great tips on CSS, AJAX and other Web 2.0 thingies...

Asynchronous JavaScript and XML, or Ajax, is a web development technique for creating interactive web applications using a combination of:
- HTML (or XHTML) and CSS for presenting information
- The Document Object Model manipulated through JavaScript to dynamically display and interact with the information presented
- The XMLHttpRequest object to exchange data asynchronously with the web server. (XML is commonly used, although any format will work, including preformatted HTML, plain text, JSON and even EBML)
