<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en"  "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd">  <html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core">  <body> #{helloworld.message}  </body> </html>

faces-config.xml

<?xml version="1.0" encoding="utf-8"?>  <faces-config 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-facesconfig_2_1.xsd" version="2.1">  </faces-config>

and web.xml

<?xml version="1.0" encoding="utf-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"   xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-  app_2_5.xsd" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="webapp_id" version="3.0"> <display-name>jsfsampleproject</display-name> <welcome-file-list>  <welcome-file>index.html</welcome-file>  <welcome-file>index.htm</welcome-file>  <welcome-file>index.jsp</welcome-file>  <welcome-file>default.html</welcome-file>  <welcome-file>default.htm</welcome-file>  <welcome-file>default.jsp</welcome-file> </welcome-file-list> <servlet>  <servlet-name>faces servlet</servlet-name>  <servlet-class>javax.faces.webapp.facesservlet</servlet-class>  <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping>  <servlet-name>faces servlet</servlet-name>  <url-pattern>*.jsf</url-pattern> </servlet-mapping> <context-param>  <description>state saving method: 'client' or 'server' (=default). see jsf   specification 2.5.2</description>  <param-name>javax.faces.state_saving_method</param-name>  <param-value>client</param-value> </context-param> <context-param>  <param-name>javax.servlet.jsp.jstl.fmt.localizationcontext</param-name>  <param-value>resources.application</param-value> </context-param> <listener>  <listener-class>com.sun.faces.config.configurelistener</listener-class> </listener> </web-app>

and when run application on apache server, page see under

localhost:8080/jsfsampleproject/ :

#{helloworld.message}

i have jsf 2.1 mojorra under libraries tab. think problem ?

thanks.

the problem welcome file list accepts file names physically present in web app, , index.xhtml. note none of welcome files match condition.

next, file not handled facesservlet. is, requested url not correspond servlet url mapping in web.xml. note mapping *.jsf doesn't match requested files well.

all in all, following excerpt web.xml solve problem:

<welcome-file-list>     <welcome-file>index.xhtml</welcome-file> </welcome-file-list> <servlet>     <servlet-name>faces servlet</servlet-name>     <servlet-class>javax.faces.webapp.facesservlet</servlet-class>     <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping>     <servlet-name>faces servlet</servlet-name>     <url-pattern>*.xhtml</url-pattern> </servlet-mapping>

of course, you'll need file index.xhtml @ root of web application.
