A JSF application needs on the following two configuration files:
1. web.xml
2. faces-config.xml
Note: Put the configuration files under WEB-INF folder.
web.xml:
Example:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<servlet>
<servlet-name>faces</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>faces</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
</web-app> |
faces-config.xml:
The faces-config.xml file contains the JSF application configuration. It can be used to configure the following:
1. Used to configure managed beans.
2. Used to configure convertors.
3. Used to configure validators.
4. Used to configure navigation.
Example:
<?xml version="1.0" encoding="windows-1252"?>
<faces-config version="2.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xi="http://www.w3.org/2001/XInclude"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">
<navigation-rule>
<from-view-id>helloworld.xhtml</from-view-id>
<navigation-case>
<from-outcome>success</from-outcome>
<to-view-id>welcome.xhtml</to-view-id>
</navigation-case>
<navigation-case>
<from-outcome>fail</from-outcome>
<to-view-id>helloworld.xhtml</to-view-id>
</navigation-case>
</navigation-rule> |
