Build your own application

This section details how to create your own JavaServer Faces application step by step. The example I use is simple. It asks the user to enter his or her name, then clicks the Submit button, and the application displays a welcome message to the user.

Create the following directory structure:

C:tomcat4.1webapps

Hello

Src

Web

WEB-INF

Web.xml

Lib

Classes

The basic idea of this directory structure is that I want to create a new application called hello. Under the helo subdirectory, there is a src subdirectory with all the Java source files in it, and a web subdirectory with a WEB-INF directory containing web.xml files and two other subdirectories, lib and classes.

Copy all the jar files in the c:jsf-ea3lib directory to the lib subdirectory we created above.

Create a web.xml file to configure our Web application. When using JavaServer Faces, you must specify several configurations, such as (1) servlet context listener, (2) the servlet used to process JavaServer Faces requests, and (3) the servlet mapping of the above servlet. The following code is a configuration file for this application.

Code 1: web.xml
