Previously I didn't mention the correct path to page which index page is navigate to and I used jsp:forward tag

Below tag which I previously used

<jsp:forward page="/faces/views/prime.xhtml"></jsp:forward>

and I changed it to c:redirect

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Index</title>
</head>

<body>
    <c:redirect url="/views/prime.xhtml"></c:redirect>
</body>
</html>

The problem was solved.

You didn't specify path to the action correctly, should be 

<html:form action="/DemoS"
