<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 . 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 FacesServlet processing must be directed to this servlet. So if we want to invoke this servlet with every request we have to do mapping in <servlet-mapping> element. This is done to map a particular URL pattern with the Faces servlet.According to this file, URL of every request must end with .jsf.

Running the application
