please help me to get rid from this error . I have tried a lot but the error message is coming .Thanks in advance .

Check out your code in web.xml, you have written,

<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.faces</url-pattern>
  </servlet-mapping>

So you can access your page by not index.jsp but index.faces
