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

[Yuri Singidas]

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();
                  }

Hi all,
       I'm using following code to upload file from servlet to client
machine for saving that in the client machine.
       But, I could only see the dialogue box with "save" "Open" "cancel".
If I click 'Open" it is reporting file corruption. If I save, I can see the
size of file as 1 byte.
       Can any one help me by pointing the mistake in the code? or correct
approach....
                       FileInputStream fo = new
FileInputStream("c:\\tech.pdf");
                       response.setContentType("application/pdf");
response.setHeader("Content-Disposition","attachment;
filename=output.pdf;");
                       javax.servlet.ServletOutputStream out =
response.getOutputStream();
                       long avl = 0;
                       while( (avl = fo.available()) != 0)
                       {
                               byte[] bytes = new byte[(int)avl];
                               out.write(fo.read(bytes));
                       }
                       out.flush();
                       out.close();
                       fo.close();


Thanks and Regards,
