How to use RichFaces4.0 with JSF2.0? How to configure View Handler for RichFaces4.0?

I am using a simple example program using RichFaces 4.0 but unfortunately I am not able to configure the view handler for Richfaces 4.0.

I have following libraries in my WEB-INF folder

commons-beanutils-1.7.0.jar commons-collections-3.2.jar commons-digester-1.8.jar commons-logging-1.0.4.jar cssparser-0.9.5.jar guava-r08.jar jsf-api-2.0.4-b09.jar jsf-impl-2.0.4-b09.jar jstl-1.2.jar richfaces-components-api-4.0.0.20110209-M6.jar richfaces-components-ui-4.0.0.20110209-M6.jar richfaces-core-api-4.0.0.20110209-M6.jar richfaces-core-impl-4.0.0.20110209-M6.jar sac-1.3.jar

What is happening is that as I do not have any view handler so when I run the application I am being prompted to download the file from the browser?

If I include jsf-facelets.jar and configure it in the faces-config.xml then i get tag lib error while deploying. The browser does not display any RichFaces4.0 component only text is displayed.

See below error for reference.
