Trying to connect to a ftp server

Question

I am able to connect to Cerberus (5.0.0.5) using the web browser or using a CoreFTP client, but I can't connect programatically using org.apache.commons.net.ftp.FTPClient. 
Below is my code (this is actually using the java ftpclient through Coldfusion) :
ftpsClient = CreateObject("java","org.apache.commons.net.ftp.FTPClient").init();
ftpsClient.connect(JavaCast("string","xxx.xxx.xxx.xxx"),21);
connected = ftpsClient.isConnected();
login = ftpsClient.login(JavaCast("string","username"),JavaCast("string","password"));
This is what I see in the ftp server log file:
2011/12/13 13:47:54  [0]  Client connected to Cerberus FTP Server 5.0.0.5 on 'machine'
2011/12/13 13:48:41  [1]  Incoming connection request on FTP interface 0 at xxx.xxx.xxx.xxx
2011/12/13 13:48:41  [1]  FTP connection request accepted from xxx.xxx.xxx.xxx
2011/12/13 13:48:45  [1]  USER svc.script
2011/12/13 13:48:45  [1]  331 User svc.script, password please 
At this point the Coldfusion/Java client returns "Truncated server reply".  I also tried not using the login, and instead sending the user command and pass command separately like this:
userCmd = ftpsClient.sendCommand(JavaCast("string","USER" ),JavaCast("string","username" ));
But as soon as I send the "USER" command I see the above in the log file and the same reply, "Truncated server reply".
When I use the cfftp tag like this:
<cfsetting requesttimeout="1000">
<cfftp action="open" connection="ftptest" secure="false"
    server="xxx.xxx.xxx.xxx" port="21"
    username="username" password-"password" timeout="1000" stoponerror="true">
I receive a "java.net.ConnectException: Connection timed out: connect"
Does anyone have any ideas?  Thanks much.

This has been resolved.
There is a bug in the apache commons ftpclient that misinterprets /r in the welcome message.  The ftp server people made a change that fixes this.
With cfftp, when I changed the server attribute on the cfftp open to the server name instead of the ip address, it started working.  To me this is a bug in ColdFusion, you should be able to use the ip address.
The other thing I noticed is when you use getfile, you have to set the the failifexists attribute to "false".  If you don't, it fails every time and the file has a "0" size, whether the file actually does exist.  To me, another bug.
