Regenerate a PDF file form ServletInputStream.

[AnhTuan Nguyen <anhtuantt (at) yahoo.com>]

Hi Bruno,

Thank you for your reply quickly,

The "regenerate" term maybe make you confuse. My problem is described below:

The PDF form is submitted to Tomcat server with PDF format, and i used the ServletInputStream (javax.servlet. to gererate the PDF file from PDF client. This is my code:

 

protected void doPost(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException {
   PrintFDF(request, response, "POST");
 }
 public void makePdf(HttpServletRequest request, HttpServletResponse response, String methodGetPost)
  throws ServletException, IOException {
  try {

   File tempFile = new File("c:\\test.pdf");
      FileOutputStream fout = new FileOutputStream(tempFile);
      BufferedInputStream bin = new BufferedInputStream(request.getInputStream());
      BufferedOutputStream bout = new BufferedOutputStream(fout);
      byte[] buf = new byte[8 * 1024];
      int len;
      while ((len = bin.read(buf)) > -1) {
          bout.write(buf, 0, len);
      }
      bout.close();
      bin.close();
  } catch (Exception e2) {    }
 }

The result file (test.pdf) is different with the original file in size and version.

 

Best regard,
Tuan
