Paul, thank you.
I will study your code.
In the meantime, I am attaching a standalone, runnable version of my
client (should have done that at the start). There is not much to it,
nor is there there a server counterpart - I don't need one until I
clear up this multipart issue. Meaning, if the client gets far enough
to encounter 'connection refused' by a server that is not there, I
will declare victory, start my server, then move onto examining what
the client actually sends.
Invoke as:
$ mvn clean package; java -jar target/conman-client-jar-with-
dependencies.jar -c -e biff_at_foo.org -d RESTandS3.pdf -m application/pdf
