The most trivial way to upload a file over SFTP with JSch is   JSch jsch   new JSch    Session session   jsch getSession user  host   session setPassword password   session connect     ChannelSftp sftpChannel    ChannelSftp  session openChannel  sftp    sftpChannel connect     sftpChannel put  C  source local path file zip     target remote path file zip      Similarly for a download   sftpChannel get   source remote path file zip    C  target local path file zip        You may need to deal with UnknownHostKey exception
