FTP exceptions during quit - due to verbose on?

Question

Dear friends,

We are using EDT FTP java package in our application to ftp to some lucent switches. Since these switches were upgraded from Fone TP server version to another our application fails for all switches except for one. These are behaviours when I quit with that one switch compared to others.

Sucessful FTP:
==========

ftp> quit
221 Goodbye.

Failed FTP
=======

ftp> quit
221-You have transferred 0 bytes in 0 files.
221-Total traffic for this session was 1838 bytes in 1 transfers.
221-Thank you for using the FTP service on ny-westbury1.
221 Goodbye.

This behavioral difference is causing FTP to fail with errors like - FileNotFoundException, FTPException, IOException etc.. and it's not consistent.

Question is: how can I make FTPClient to work successfully irrespective of what output I see after quit. We do settings like BINARY, PASV etc., Is there something like that can be done?

Your help appreciated in advance.

Thank you
- John

Answer 1

This should work - if not, it is a bug.

Can you post a log file please (with DEBUG level) & we will try to figure out what the problem is. If you aren't using the latest version (1.5.1), please upgrade also.

Bruce,

Thanks for the response. Here's the log:

That was one sample I am getting now. Here are other types of exceptions I am seing.

I am not sure what version we are using. Is there a way I can check?

thanks,

Answer 3

You can get the version number by unjaring the edtftp.jar file and looking in the manifest.

These are stack traces, you should be able to also get a log file - see the Developers Guide or the demo code in the demo directory for how to capture logging info.

Timeout exceptions are because your connection timed out - the FTP server has terminated your connection.
