The Sun Blueprints project hosted by has started to address 'Asynchronous JavaScript and XML (AJAX) with Java 2 Enterprise Edition' to enable dynamic web applications. From the Blueprints:

We have seen that there are many possible problems that AJAX interactions can solve. J2EE technology provides a good base to develop and deploy AJAX based applications with APIs for tying in HTTP processing, databases, web services, XML processing and business objects. With a better understanding of this interaction model, today's applications can become more interactive providing a better experience to the end user.

Use cases indicating appropriate use of AJAX, according to an explanatory document, include:

* Realtime form data validation
* Auto-completion in HTML controls
* Master/detail page interactions that might not otherwise require complete page redraws
* Sophisticated UI controls
* Data refreshes for limited data (i.e., scores, forecasts, or stock prices)
* Server-side notification polling"
