RichFaces Architecture
The architecture of RichFaces consists of an Ajax filter, Ajax action components, Ajax containers, and a JavaScript engine.
- Ajax filter - In order get all benefits of RichFaces, a developer should register a filter in the web.xml file of the application. The filter recognizes multiple request types.
- Ajax action components - AjaxCommandButton, AjaxCommandLink, AjaxPoll and AjaxSupport and other action components can be used to send Ajax requests from the client side.
- Ajax containers - AjaxContainer is an interface that describes an area on a JSF page that should be decoded during an Ajax request. AjaxViewRoot and AjaxRegion are implementations of this interface.
- JavaScript engine - the RichFaces JavaScript engine runs on the client-side. It updates different areas on a JSF page based on the information from the Ajax response. The JavaScript engine provides an API so developers do not need to create their own JavaScript functionality.

Famous quotes containing the word architecture:
“Polarized light showed the secret architecture of bodies; and when the second-sight of the mind is opened, now one color or form or gesture, and now another, has a pungency, as if a more interior ray had been emitted, disclosing its deep holdings in the frame of things.”
—Ralph Waldo Emerson (1803–1882)
