For those of you who were not able to attend our JavaOne 2007 hands-on lab, the lab is now available online at http://developers.sun.com/learning/javaoneonline/j1labs.jsp?track=8&yr=2007.
The lab starts off showing how to use dynamic faces Ajax zones to easily enable plain old JavaServer Faces components to send Ajax requests, and, in turn, dynamically update other components with the Ajax response. You also use an Ajax Transaction to continually poll the server. When you have completed the exercise, you have a simple chat room, like the one shown above. In the instructor-led lab, we had the web app running on the demo machine so you could watch us chatting with the lab attendees. The lab file contains an older version of the dynamic faces component library. To get the more recent one, see Installing the Currency Trader Sample Application at the NetBeans Visual Web Application documentation page.
In the second part of the lab, Winston and the Andersons show how to build a JavaServer Faces component from scratch, and use dynamic faces internally to Ajaxify the component.
