JSF navigation in a HTML DIV element without reloading the entire page

I would like to know if it's possible to make JSF navigation rules inside a <div> without reloading the entire page, in an Ajax fashio开发者_运维百科n (like as in Gmail).

Suppose you have your application main page with this situation:

<div id="main"> 
  <div id="header"></div>
  <div id="menu"></div>
  <div id="content"> 
    (JSF navigation inside this div)
  </div>
</div>

Thanks in advance for reply.

JSF 2.0 has built-in ajax-functionality.

If working with JSF 1.2 - RichFaces provides such ajax functionality, using the reRender attribute which specifies which parts of the page to redisplay.
