The file faces-config.XML

The faces-config.XML is the central configuration file of JavaServer faces. In this file you define the workflow of the application (on which action which site will be processed) , the managed bean classes by JSF and something more.

The workflow of the library application looks like the following.

Java/国外教程下载/LaLiLuna%20-%20Tutorials%20for%20struts,%20ejb,%20myeclipse%20»%20First%20Java%20Server%20Faces%20Tutorial.files/workflow.gif" width=400 align=left border=0 name=Graphic7>

We define a navigation rule for this workflow.

Open the file faces-config.XML and add the following configuration.
