What
is JSF?
Java Server Faces
JSF
technology is a framework for developing, building server side User Interface
Components and using them in a web application.JSF technology is based on the
Model View Controller (MVC) architecture for separating logic from
presentation.
What is MVC Design Pattern?
MVC
design pattern designs an application using three separate modules:
|
Module
|
Description
|
|
Model
|
Carries
Data and login
|
|
View
|
Shows
User Interface
|
|
Controller
|
Handles
processing of an application.
|
Purpose of
MVC design pattern is to separate model and presentation to enable developers
to set focus on their core skills and collaborate more clearly.
Web
Designers have to concentrate only on view layer rather than model and
controller layer. Developers can change the code for model and typically need
not to change view layer. Controllers are used to process user actions. In this
process layer model and views may be changed.
Benefits Of JSF
JSF has various benefits these are as :
- The MVC architecture facilitate to separate the behavior
from presentation.
- JSF provides the facility to link the separate pieces of the
development process to a single piece by offering a simple programming
model.
- JSF provides the built-in support of Ajax, bookmarking, and
page-load actions.
- Provides more security.
- Reusability of codes.
JSF Integration
JSF can be integrated with other frameworks
like, Spring, JDBC etc.
Basic
JSF Tags

These tags get rendered into corresponding html output.
For these tags you need to use the
following namespaces of URI in html node.
<html
xmlns="http://www.w3.org/1999/xhtml"
