JSF HelloWorld The requested resource () is not available

Question

I'm trying to make HellowWorld app with JSF. I make Dynamic web proj, choose JSF v 2.0 for configuration, then Disable library configuration. Then I add jsf-api.jar, jsf-impl.jar, jstl-api.jar and jstl-impl.jar to my lib folder. Then create simple jsp and when try to start it i get The requested resource () is not available. I think it's something with the mapping of the Faces Servlet in web.xml.

You need to ensure that the FacesServlet is mapped in web.xml and that the request URL (which appears in browser address bar) matches the <url-pattern> of the FacesServlet.

E.g., if you have a simple.jsp file in webcontent and the FacesServlet is mapped on an <url-pattern> of *.jsf, then you need to open it by http://localhost:8080/contextname/simple.jsf.

<servlet>
    <servlet-name>facesServlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>facesServlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>

Unrelated to the concrete problem: why would you ever prefer the legacy/discouraged JSP over its modern successor Facelets which is the standard view technology since JSF 2.0?
