可以用下面两个重载的方法this.getAppletContext().showDocument(URL url)

同上
AppletContext appletcontext = applet.getAppletContext();
        URL url = null;
        try
        {
            url = new URL(s);
        }
        catch(MalformedURLException malformedurlexception)
        {
            DisplayMsg(malformedurlexception.getMessage());
        }
        appletcontext.showDocument(url, "_self");
