How to make make an ajax call using JSF components

Hi,
I am learning Java.
I want to know from you people that anyone here have any Idea how to make an ajax call using JSF (Java Server Faces) components?

Please help me!

AJax (Asynchronous JavaScript and XML) is one of the hot technologies on the web. It allows web developers to dynamically update content on their web pages with out ever refreshing. Ajax works behind the scenes producing requests over the Internet without the end-user even knowing. Designing applications that take advantage of this technology is the wave of the future.
