Apache Commons FTP Error

[jsulman]

Greetings,
Has anybody used the Apache Commons api for FTP?

I am trying to get a list of files on a unix box via ftp and by this simple method:

FTPClient ftp = new FTPClient();
try{
ftp.connect(server);
ftp.login(userId, password);
FTPFile[] files = ftp.listFiles(folder);
} catch(Exception e) {
e.printStackTrace();
}

and I get the following error when I perform the listFiles method.
Does anybody know what is going on?

Thanks in advance

Steerforth
