A problem with servlet file transfer

[Pham Minh An]

I am a new Java programer. I have a example for sent file.(word file. Using ms-word 2003). The file is downloaded successful but it can't open. The ms-word messages are: "Word experienced an error trying to open the file. Try these suggestions......". This's my code:

int DEFAULT_BUFFER_SIZE = 20240*1000;

        ServletOutputStream out = response.getOutputStream(); 
        response.setContentType("application/octet-stream");
        response.addHeader("Content-Disposition", "attachment; filename=test.doc");

        String pathFile = request.getSession().getServletContext().getRealPath("/upload/");

        File file = new File(pathFile, "/test.doc");

        if (!file.exists()) {
            System.out.println("File does not exits!!!");
            return;
        }

        String contentType = getServlet().getServletContext().getMimeType(file.getName());

          response.reset();
            response.setBufferSize(DEFAULT_BUFFER_SIZE);
            response.setContentType(contentType);
            response.setHeader("Content-Length", String.valueOf(file.length()));
            response.setHeader("Content-Disposition", "attachment; filename=\"" + file.getName() + "\"");

            BufferedInputStream input = null;
            BufferedOutputStream output = null;

            try {
                // Open streams.
                input = new BufferedInputStream(new FileInputStream(file), DEFAULT_BUFFER_SIZE);
                output = new BufferedOutputStream(response.getOutputStream(), DEFAULT_BUFFER_SIZE);

                // Write file contents to response.
                byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
                int length;
                while ((length = input.read(buffer)) > 0) {
                    output.write(buffer, 0, length);
                }
            } finally {
                // Gently close streams.
                close(output);
                close(input);
            }

The word file template's content: text and image(jpg). The file size: 116KB. i am looking forward to hearing from you.
Thanks...

"The file is downloaded successful but it can't open"

are you sure the file is correct? I think your client receives an empty file...or with junk in it...

save the file on the client and check its content...if its not good, there must be a problem with your original file, or your servlet's code!

Thanks for reply, olivier dutranoit. If the file's content are only text, it's ok. But, If i insert images or new lines, the error message is display.

A post that goes unanswered usually means that you have not provided enough information on the problem. So rather than posting useless bumps like that last one, provide more information that can help solve the problem.

For example, what have you done too ensure that the file is correctly formatted? How is the file being generated in the first place? And so on.
