Resume file transfer for a halfway failed file transfer with JSch

I am using this JSch library (http://www.jcraft.com/jsch/) in my ColdFusion application. My application wants to implement a retry mechanism – if a file transfer fails halfway through then I want to resume (or continue) the file transfer from where it left off. Is this possible to achieve using this JSch library?

Just reconnect and start an upload again with RESUME flag:

channelSftp.put(src, dst, ChannelSftp.RESUME);

The RESUME flag will make JSch query size of a partial remote file and restart the transfer from there. If the file is already uploaded completely, it transfers nothing.
