Re: Problem with Uploading file from Servlet to Client machine.

Try this,

           File f = null;
           f = new File(pdfFolder+"/tech.pdf");

            if (f.exists()){
                  ServletOutputStream  out = response.getOutputStream ();
                  response.setContentType( "application/pdf" );  // MIME
type for pdf doc
                 response.setHeader("Content-Disposition","attachment;

         filename=output.pdf;");

                  BufferedInputStream  bis = null;
                  BufferedOutputStream bos = null;

                  try {

                     // Use Buffered Stream for reading/writing.
                     bis = new BufferedInputStream(new FileInputStream(f));
                     bos = new BufferedOutputStream(out);

                     byte[] buff = new byte[2048];
                     int bytesRead;

                     // Simple read/write loop.
                     while(-1 != (bytesRead = bis.read(buff, 0,
buff.length))) {
                         bos.write(buff, 0, bytesRead);
                     }


                   } catch(final MalformedURLException e) {
                           System.out.println ( "MalformedURLException." );
                           throw e;
                   } catch(final IOException e) {
                           System.out.println ( "IOException." );
                           throw e;
                   } finally {
                           if (bis != null)
                               bis.close();
                           if (bos != null)
                               bos.flush();
                               bos.close();

                   }
