Jetty: Serving static files from a directory

          Server server = new Server(8080);
          Context ctx = new Context( server, "/", Context.SESSIONS );

          ServletHolder servletHolder = new ServletHolder(new WicketServlet());
          servletHolder.setInitParameter("applicationClassName", WicketApplication.class.getName() );
          ctx.addServlet( servletHolder, "/bot/*" );

/* Static content is not being served. You need to add a servlet
   that will serve the html, images etc for you: */
ServletHolder defaultSH = new ServletHolder(new org.mortbay.jetty.servlet.DefaultServlet());

// This didn't work - see the NPE bellow.
//defaultSH.setInitParameter("relativeResourceBase", "./src/main/java/org/jawabot/web/files");
defaultSH.setInitParameter("resourceBase", "./src/main/java/org/jawabot/web/files");
ctx.addServlet(defaultSH, "/");

Strange thing is that resourceBase works when provided with a relative path, and setting relativeResourceBase didn't work, I was getting this NPE:
