I am not sure I understand your question properly. Any Java library
which implements sftp or scp's protocols will have a means to copy
remote files or at least open remote files and obtain an InputStream

If you need to do the transfer on a regularly basis maybe rsync is
better than cooking your own version of it.

Thanks for the response Robert. rsync is not an option. I cannot use
any outside software, open-source or otherwise. I believe you stated

scp and sftp are non trivial to implement.

If reading chunks is a problem, then you will not be
able to implement them.

You need to get whoever made that rule give you
permission to use a library that support one of
those protocols.
