AjaxWorld Special: Creating AJAX and Rich Internet Components with JSF

AJAX has gained momentum primarily due to the "XMLHttpRequest" browser object which supports asynchronous communication

Apr. 6, 2006 09:30 AM

A JSF component developer could take advantage of XUL's presentation layer and AJAX for communication, creating a highly interactive component. If the client does not support XUL, the application can dynamically fall back to a non-XUL solution. The application developer will still be able to build one application supporting multiple rendering technologies with one common programming model - JavaServer Faces.

A Page in JSF Supporting XUL and AJAX
The JSF sample shown in Listing 7 illustrates what a page developed with reusable JSF components leveraging XUL and AJAX as rendering technologies can look like.

Apart from the obvious namespaces, the sample contains one namespace that maps to a custom component library - xmlns:bobh=" http://www.bob.org/jsf/html" - and a custom component - <bobh:inputDate ..."/>.

The source of the page is not that different from what we have seen so far with XUL or AJAX, but the main difference is that the Web application developer will not need to learn two ways of supporting Rich Internet Applications in today's browsers.

Summary
This article provides some insight into two of the market's leading view technologies for Rich Internet Applications (RIA) - XUL and AJAX. These technologies have proven that they are more than capable of providing the end user with a highly rich and responsive user interface. We have also touched on the issues with these technologies such as platform support, being non-standards based, and maintenance.

Looking ahead, the potential for JavaServer Faces as a UI component technology is without boundaries. Component developers can provide the community with a wide range of components supporting technologies from HTML to XUL, wireless, and even character-based solutions with the imagination as the only limit.

In future articles, we are going to discuss how to build reusable JSF components that leverage AJAX and XUL.

This article is based on, and contains excerpts from, the book Pro JSF: Building Rich Internet Components by Jonas Jacobi and John Fallows, published by Apress. Book is now on bookstores and Amazon as of February 25, 2006.
