hi,

first of all: you should put something into the=20

=46TPClient connection =3D null;
       =20
        try
        {
            int reply;
            connection =3D new FTPClient();
            connection.connect("remotehost"); //put in your server

            // After connection attempt, you should=20
            // check the reply code to verify success.
            reply =3D connection.getReplyCode();

            if(!FTPReply.isPositiveCompletion(reply))
            {
                connection.disconnect();
                throw new IOException("Could not connect to Server: " +=20
                        connection.getReplyString());
            }

            boolean success =3D connection.login("username", "password");

            if (!success)=20
            {
                // Error while trying to login
  // some reporting
            }
    else
    {
  // we are logged in
  }
=2E
=2E
=2E
=2E

that is not exactly the code i'm using but it should point you in the right=
=20
direction. first i would try to get the replycode. if it is an error than=20
check the reply string (FTPClient.getReplyString() method).
