For anyone who have this problem with commons-net, use ftp4j library instead, and it will solve your problem. — skystar7, Jan 24 '13 at 21:11

Hard to say, try adding a protocol Listner (before the client.connect() to get some more info:

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