Faces Servlet Configuration

Faces Servlet Configuration

When a user requests the login page (or any JSF page) via URL entered in their browser, the request is routed
to a JSF servlet call the Faces Servlet. There is only one instance of the Faces Servlet. Specifically, it is the
javax.faces.webapp.FacesServlet. All requests for JSF pages are processed by this special servlet. The Web
container knows to route all traffic to the Faces Servlet by adding a servlet mapping to the standard web.xml
file.

web.xml

<web-app>
  <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>/faces/*</url-pattern>
  </servlet-mapping>
</web-app>

In this example, any URL that has a pattern like http://localhost:8080/[App context]/faces/[any page].jsp gets
routed to the Faces servlet.
