If it cannot be placed at a public URL, then the DB2 service needs to
provide a mechanism to distribute the db2jcc.jar file.

If the MobileFirst charm is able to open a database connection to DB2, then
you may be able to use the DB2 database connection to retrieve the file
from the remote container.

Alternatively, the ssh protocol is available on all containers. If you can
set up suitable access, then the MobileFirst charm could scp the jar file
from the DB2 service. If you don't mind Python code, contrib.unison in the
charm-helpers project might be helpful. It sets up ssh authorization in a
peer relation, but perhaps could be adapted to set up ssh authorization
between your two services.
