Error while downloading a file

Question

I have written a servlet that downloads a file from my server on to my mobile.
i have written the following code to download the file:
URL url = new URL(path);
                    URLConnection connection = url.openConnection();
                    InputStream stream = connection.getInputStream();
                    BufferedInputStream in = new BufferedInputStream(stream);
                    FileOutputStream fos = new FileOutputStream(fileName);
                    BufferedOutputStream out = new BufferedOutputStream(fos);
                    int i;
                    while ((i = in.read()) != -1)
                        //System.out.println("Reading the file");
                        out.write(i);
                    out.flush();The code has no errors, but i m unable to download the file. The mobile gives me an error saying:
Services: Empty File
Can anyone please help me out with this problem.
with regards,
Shirish

Answer 1

This way to download files from server looks odd. You're issuing a new URL connection, likely to self. This may be slower than accessing the file directly using FileInputStream.
But anyway, you haven't set the contenttype and contentlength accordingly. Likely the mobile is aborting the download immediately since the headers have sent a contentlength of 0 bytes.
Check at the bottom of http://balusc.xs4all.nl/srv/dev-jep-pdf.html for some downloadFile() snippets, which might provide useful insights how to download files.
