In the case of PHP, you can effectively enable AJAX in your apps using jQuerys $.getJSON() and PHP json_encode().

I think we can use a very similar approach for Java web applications, enabling the use of AJAX through a very simple, elegant and extensible architecture, without the use of complex frameworks and extra configurations.
