Hi,

Thanks for the help.  The writeString method below works well but the
writeFile method does not.  The writeFile method executes but data are
not sent to the client.  The files I am sending are small so it
shouldn't be an issue for this application but it would be nice to get
the file method to write data to the client.

Thanks again,

       String string) throws Exception {
       response.setContentType("application/x-download");
       response.setHeader("Content-Disposition",
               "attachment; filename=certificate.txt");
       PrintWriter out = response.getWriter();
       out.write("hello world");
   }

   private void writeFile(HttpServletResponse response, String string)
           throws Exception {
       response.setContentType("application/x-download");
       response.setHeader("Content-Disposition",
               "attachment; filename=certificate.txt");

       OutputStream out = response.getOutputStream();
       InputStream in = new ByteArrayInputStream(string.getBytes());
       int bufferSize = 1024;
       BufferedOutputStream dest =
         new BufferedOutputStream(out, bufferSize);
       int count = 0;
       byte[] data = new byte[bufferSize];
       System.out.println("writing data");
       while ((count = in.read(data, 0, bufferSize)) != -1) {
           dest.write(data, 0, count);
           System.out.write(data, 0, count);
       }
       System.out.println("");
       out.flush();
       out.close();
