hi,

first of all: you should put something into the 

FTPClient connection = null;
        
        try
        {
            int reply;
            connection = new FTPClient();
            connection.connect("remotehost"); //put in your server

            // After connection attempt, you should 
            // check the reply code to verify success.
            reply = connection.getReplyCode();

            if(!FTPReply.isPositiveCompletion(reply))
            {
                connection.disconnect();
                throw new IOException("Could not connect to Server: " + 
                        connection.getReplyString());
            }

            boolean success = connection.login("username", "password");

            if (!success) 
            {
                // Error while trying to login
  // some reporting
            }
    else
    {
  // we are logged in
  }
.
.
.
.

that is not exactly the code i'm using but it should point you in the right 
direction. first i would try to get the replycode. if it is an error than 
check the reply string (FTPClient.getReplyString() method).
