FTP file upload problem

843789 Newbie

I am trying to upload a file to an FTP server. It seems that relatively small files like under 2MB uploads just fine but
for example 6MB files don't make it to the server. I know this could be done with the storeFile (don't know if that works
either) but I want to keep track how many bytes has been send so I can update my progressbar.
JakartaFtpWrapper x = new JakartaFtpWrapper();
x.connectAndLogin (server, username, password);
x.binary(); // sets binary transfer

File file = new File(fileName);         
InputStream is = new FileInputStream(file);
OutputStream os = x.storeFileStream(fileName);

byte[] buffer = new byte[1024];
int len;
double progress = 0;
long fileSize = file.length();          

while ((len = != -1) {
     progress += len;
     percent = (int) (progress/fileSize*100);
     os.write(buffer, 0, len);
Why can't I transfer large files :( ?
Is there a better way to upload the file and monitor the progress? (don't want any pop up dialogs with progress bars)

Thank You for answers

    Who says it is a code problem?

    Did you try uploading a large file to this server using FileZilla or WinSCP or any other FTP client?

    By the way: what do you mean by "doesn't make it". Does the upload stall, or do you get an exception?
