HelloWorld Demo

It has been reported to me that this launcher contains a virus. It's an old project, so I've disabled it. Here is the code that used to appear in this page:
  
  <...script language="JavaScript">
    /* Gecko (Netscape/Mozilla): link to the application's JNLP file.
     * IE: Link to download page to auto-download-and-install JRE,
     *     if needed, and then launch the app.
     */
		var javawsInstalled = 0;
    if (navigator.userAgent.indexOf("Gecko") !=-1) {
       if (navigator.mimeTypes && navigator.mimeTypes.length) {
           if (navigator.mimeTypes['application/x-java-jnlp-file']) {
              javawsInstalled = 1;
           }
        }
        if (javawsInstalled) {
           /* Non-IE browser, JRE present */
           document.write("Click here ");
           document.write("to launch the application.
"); document.write("(It will be downloaded if it isn't already installed.)"); } else { /* Non-IE browser, JRE absent */ document.write("

"); document.write(""); document.write("Download the Java Runtime Environment (JRE) from the "); document.write("Java download page. "); document.write("Then reboot and come back to this page to launch the application."); document.write("

"); document.write("Note:

"); } } else { /* Internet Explorer */ document.write("Click here "); document.write("to run the application. "); document.write("
