title: How can I change permissions of a file on a ftp server using apache commons net ftp?
body: <p>If have a list of ftp files from a server, how can I change the permission on one of these files? </p>
  
  <p>If someone can point me to a tutorial or show me an example I would be grateful. I have figured out how to change the permission in the file but not how to make the change permanent on the server. </p>
  
  <p>Any suggestions?</p>
