16 Aug 2006 This tutorial shows you how to use WebSphere® Portal to create and deploy a portlet that contains AJAX functionality.
Objectives - Learn how to implement Ajax into a portal-based Web application.
- Discover how to dynamically update a page using DHTML.
Prerequisites
This tutorial is intended for experienced WebSphere Portal developers. It is assumed that you have a general knowledge of Java® Portlet (JSR 168) development, JavaScript, HTML, CSS, and XML. You should also have a basic understanding of WebSphere administration and portal application deployment using Rational tooling or the portal administrative console.
System requirements
Before beginning this tutorial, ensure that:
- You have IBM® Rational® Application Developer (RAD), or a similar tool, to edit and deploy the portal application. Although this tutorial assumes that you are using RAD, nothing contained within this tutorial is tooling specific. You can use any preferred editor or method for deploying the portlet WAR file into WebSphere Portal.
- You have WebSphere Portal v5.x or later installed.
- You have a database installed, such as DB2®.
Duration

Summary
Asynchronous JavaScript and XML (Ajax) is the latest buzzword in the Web development world. Going beyond the hype, this tutorial will address how to effectively use this powerful client-server interaction paradigm in your portal applications. First, we will get into a brief introduction to Ajax and how it interacts with DHTML (Dynamic HTML -- JavaScript, CSS, DOM). Next, we will get into an architectural discussion of a basic Ajax-enabled portal application. Finally, we will jump into building a working example that will reinforce your understanding of Ajax.
