<h:commandButton action=”result”
value=”#{message.button_text}” />

Here action attribute is set to “result”. When user presses the command button then which page will be displayed is determined by the navigation rule defined in faces-config.xml configuration file. This rule has been defined like this for our application:

<navigation-rule>
<from-view-id>/pages/inputname.jsp</
from-view-id>
<navigation-case>
<from-outcome>result</fromoutcome>
<to-view-id>result.jsp</to-view-id>
</navigation-case>
</navigation-rule>

<navigation-rule> defines navigation rule. <from-view-id> is used to specify the jsp file for which navigation rule is to be defined. Here in our application it is inputname.jsp that is in pages folder. <navigation-case> specifies the value which is matched with the value specified in action attribute of commandButton tag. If it matches then the page specified within <toview- id> tag is displayed. Here in our application it is “result.jsp”.

So after editing faces-config.xml file, it will look like following:

<?xml version=”1.0"?>
<!DOCTYPE faces-config PUBLIC
“-//Sun Microsystems, Inc.//DTD JavaServer
Faces Config 1.1//EN”
“http://java.sun.com/dtd/webfacesconfig_
1_1.dtd”>
<faces-config>
<managed-bean>
<managed-beanname>
StoreNameBean</managed-beanname>
<managed-bean-class>
javajazzup.PersonBean</managed-beanclass>
<managed-bean-scope>request</

managed-bean-scope>
</managed-bean>
<navigation-rule>
<from-view-id>/pages/
inputname.jsp</from-view-id>
<navigation-case>
<from-outcome>result</fromoutcome>
<to-view-id>result.jsp</to-viewid>
</navigation-case>
</navigation-rule>
</faces-config>

Editing web.xml:

The “FacesServlet” servlet handles JSF applications. So as we are using JSF framework in our web application, we will edit the deployment descriptor file web.xml to define “FaceServlet” and its mapping in web.xml file.

<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servletclass>
javax.faces.webapp.FacesServlet</
servlet-class>
<load-on-startup> 1 </load-on-startup>
</servlet>
<!— Faces Servlet Mapping —>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>

<servlet> element maps the “javax.faces.webapp.FacesServlet” servlet class to a symbolic name i.e. Faces Servlet is an alias for “javax.faces.webapp.FacesServlet” servlet .<servlet-mapping> element is used to map any request of pattern like .jsf in the URL must be passed to the Faces servlet. The FacesServlet servlet works as an engine for all JSF applications( handling of all JSF related requests, building component tree of the JSP page, accessing all JSP pages in the application, creating an Event object and passing it to any registered listener). So all requests that need
