RichFaces Java Question

Hi,
I am new to RichFaces. I was wondering how the following could be done in RichFaces
* When a selection is based on the drop-down menu
* It calls a Java Function which returns data.
* Data should be rendered on the same page.in a data table w/ a scroller.

I looked at Data Scroller demo in the following link, which give me a good idea how to create a data table using AJAX requests.
http://livedemo.exadel.com/richfaces-demo/richfaces/dataTableScroller.jsf?c=dataTableScroller&tab=usage

How can I make it work with a Java Function?
(OR)
Should I make the Java Function & the class act more as a Web Service that just returns the data?
(OR)
something else

Please state your suggestion(s) and give sample code that can assist your suggestions.

Thanks,
P

I think what you need is to use the a4j tag
