Question

Hello I am using Apache Commons FTP Client and I want to show the FTP Commands that the FTP Client uses so like when I use changeWorkingDirectory it should show me the FTP Command that it used like: CODEOFCOMMAND CHD …..

or when I upload a File it should show me: CODEOFCOMMAND PUT ….

Is there any possibility to do this ?

You can find it in the Apache Commons Net FAQ :

A: You can add a protocol command listener; for example:

ftp.addProtocolCommandListener(new PrintCommandListener(new PrintWriter(System.out), true));
