     document.setPageSize(PageSize.A4.rotate());
     OutputStream out1 = response.getOutputStream();
     response.addHeader("Content-Type", "application/pdf");
     response.addHeader("Content-Disposition", "attachment; filename=\"Test.pdf\"");
          try {
               URL yahoo = new URL("http://localhost:8080/Test/HelloWorld.faces");
               URLConnection yc = yahoo.openConnection();
               BufferedReader in = new BufferedReader(
               new InputStreamReader(
               yc.getInputStream()));
          PdfWriter.getInstance(document, out1);
          HtmlParser.parse(document, yc.getInputStream());
          catch (Exception e) {
          System.out.println("error="+e);
          e.printStackTrace();
