problems with rich:datascroller

[giacomino]

Hi to everybody, I'm a newbie of Jboss tecnologies.
I'm developing a project that use the rich:datascroll component.
I have integrated the richfaces-ui-3.2.2.GA.jar library in my developer tool and when i run the application on the server appears the following exception:

]] Root cause of ServletException.

I don't understand why the system don't find the taglib DatascrollerTag.
Can you help me to resolve this my problem? I'm desperate!!!
Thank's to everybody

Ps. I think it's not very important but I'm using the Jdeveloper like developer tool.

Hi Giacomo,

Try h:form instead of af:form.
