Configure embedded jetty with web.xml?

I am trying to generate both a war with my web application as well as a self contained jar file with embedded jetty. For the embedded jetty (the jar file distribution) I add a servlet as follows:

public static void main(String[] args) throws Exception {
    Server server = new Server(8080);

    ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
    context.setContextPath("/");
    server.setHandler(context);

    context.addServlet(new ServletHolder(new HelloServlet()),"/*");

    server.start();
    server.join();
}

The war file distribution uses a web.xml file that contains the following in the web-app section:

<servlet>
    <servlet-class>com.example.HelloServlet</servlet-class>
    <servlet-name>SimplestServer</servlet-name>
</servlet>
<servlet-mapping>
    <servlet-name>HelloServlet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

This works. However, I want to get rid of the duplication between the two approaches. I.e., when I add a new servlet I want to have to configure it in only one location. Can I load and use the web.xml file from the embedded jetty?
