java - How to uplaod file in sftp from a host to another host in sftp

Question

I need to connect to one host directory in sftp and copy all files to another host directoy in sftp. I need first to createChannelSftp.

private ChannelSftp createChannelSftp() {
        try {
            JSch jSch = new JSch();
            Session session = jSch.getSession(username, host, port);
            session.setConfig("StrictHostKeyChecking", "no");
            session.setPassword(password);
            session.connect(sessionTimeout);
            Channel channel = session.openChannel("sftp");
            channel.connect(channelTimeout);
            return (ChannelSftp) channel;
        } catch(JSchException ex) {
            logger.error("Create ChannelSftp error", ex);
        }

        return null;
    }

I have properties files when I have :

 host : 1X.XXX.XXX
 username : admin
 password : xxxxx
 port : 22

and another properties file with :

 host : acp.toa.ad.com
 username : admin
 password : xxxxx
 port : 31017

For the first one with ip adress it works but not the second with dns name is it normal ? For both of them I can access to sftp with winscp.
