Connection Reset Error with Commons FTP

Hi all,

I'm using Commons FTP to upload file. The API works fine but for some reason
i get the following error occasionally. I have added the error trace and the
code that i use to send the file using FTP.

What Puzzles me is that the FTP API throws Error but the file is still
copied correctly to the Host.

Can i just ignore this error or is it that something is wrong.

try{
          FtpClient ftpClient = .....
          ftpClient.enterLocalPassiveMode();
          ftpClient.storeFile(directoryName + fileName, stream);
}catch(Exception ...){
        ..............
} finally {
            disconnect ftp....
}


Stack trace .........

The api documentation for the FTP class provides some advice for handling
connections that are prematurely closed. I'd also verify the version of
Commons Net because the TelnetClient is not used in the current 1.4.1
version of the FTP class. A version of FTP that extends SocketClient instead
of TelnetClient may handle connections better.

What version of Commons Net are you using? Looks like an older one. Try a
newer version, either 1.4.1 or 2.0.
