JSF:
JSF provides standard, reusable components for
creating user interfaces for web applications.
JSF provides many tag libraries for accessing and
manipulating the components.
It automatically saves the form data and repopulates
the form when it is displayed at client side.
JSF encapsulates the event handling and component
rendering logic from programmers, programmers just
use the custom components.
JSF is a specification and vendors can develop the
implementations for JSF.
There are many GUIs available these days to simplify
the development of web based application based on
JSF framework.
COMPONENTS
