WHAT IS JSF?

A standard Java framework for building Web applications.

It simplifies development by providing a component-centric approach to developing Java Web user interfaces.

JSF applications are event driven.

JSF ARCHITECTURE:

JSF LIFECYCLE

BENEFITS OF USING 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

The true power of JSF in its user interface component model where applications are merely built from collections of components that can render themselves in diverse ways for multiple client types.

A simple component: Input Text:

EXAMPLES OF COMPONENTS:1. Menu component

2. Media component

3. Table component
