As Morten says, the files should be stored under '$DHIS2_HOME/documents'.
There is no intent to store them in the WAR file itself for production
instances. That would be pretty silly. It might be a fallback though (which
is probably in place for testing purposes).

In answering your comments on where and how the files are stored:
This is a pretty classic problem in database design. And there certainly is
no 'correct' way to do it. We've elected to keep large binary files out of
the DB to avoid bloat (it's already huge for many DHIS 2 instances).

Most importantly, storing large files in the DB can incur huge storage
costs for instances running off of SSDs. Serving files can in those cases
be done from a separate (much cheaper) disk or location, which makes a lot
of sense. Of course, this has some major drawbacks as well, especially in
terms of adding to maintenance complexity. It's a tradeoff.
