The Controlling Servlet

The URL triggering this servlet is "dateAndTime.ajax".

It cannot be handled by the normal JavaServer Faces servlet configured in web.xml:

   <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>  

Instead, we add:

    <servlet>
        <servlet-name>Ajax Servlet</servlet-name>
        <servlet-class>com.corejsf.AjaxServlet</servlet-class>
    </servlet>

    <servlet-mapping>
        <servlet-name>Ajax Servlet</servlet-name>
        <url-pattern>*.ajax</url-pattern>
    </servlet-mapping>
