JavaServer Faces technology consists of the following:
An API for representing components and managing their state; handling
events, server-side validation, and data conversion; defining page
navigation; supporting internationalization and accessibility; and
providing extensibility for all these features
Tag libraries for adding components to web pages and for connecting
components to server-side objects
JavaServer Faces technology provides a well-defined programming model
and various tag libraries. The tag libraries contain tag handlers that
implement the component tags. These features significantly ease the
burden of building and maintaining web applications with server-side
user interfaces (UIs). With minimal effort, you can complete the
Create a web page.
Drop components onto a web page by adding component tags.
Bind components on a page to server-side data.
Wire component-generated events to server-side application code.
Save and restore application state beyond the life of server requests.
Reuse and extend components through customization.
This chapter provides an overview of JavaServer Faces technology. After
explaining what a JavaServer Faces application is and reviewing some of
the primary benefits of using JavaServer Faces technology, this chapter
describes the process of creating a simple JavaServer Faces application.
This chapter also introduces the JavaServer Faces lifecycle by
describing the example JavaServer Faces application and its progression
through the lifecycle stages.
