Summary: In our previous article, Using Ajax with WebSphere Portal, we discussed some issues and design concerns when using Ajax in a portal application. In this tutorial, we will put our newfound knowledge to use and create an Ajax portlet application. To make things interesting, we decided to build a portlet that makes heavy use of Ajax and DHTML. This provides you a glimpse into what's possible with this technology, and to also give you a useful tool to browse your databases. While most of the application is already written, it is up to you to fill in the blanks to get things running.
