      Perfect! Thanks for the confirmation.

That was it - I was still changing the war config instead of the .basex
for the server after changing from 7.3 to 7.5 even though I had started
using the basexhttp server instead.
Thank you! I really look forward to testing our system with basex, I
expect a vast improvement in speed based on an alpha build I've been
playing with on the windows side.

Hi Michael,
with 7.5, there are several, alternative options to start the BaseX
HTTP Server, which are listed at [1]. You either need to deploy the
WAR file, or run basexhttp.
a) if you deploy the WAR file, your databases will be contained in the
archived webapp directory. With the latest snapshots, the database
server will be automatically started along with the web server
b) if you run basexhttp, you can specify DBPATH and the path to the
webapp directory (WEBPATH) in the .basex configuration file.
Hope this helps, feel free to ask for more,
Christian

I am running the 7.5 snapshot now, which has been a bit easier to work
with,
but I still end up stuck in the same place.
Ultimately, I would like to be able to:
    run basex from a cli
    offer REST
    be able to interact with the db via python without using REST (so I
can
perform maintenance with it off and maintain separation of duties)
    and have all of these actions performed against the same database
I know client spawns a different instance, so I have no plans to use
it. As
far as I can tell, I should be able to do all of this. I can execute
basex
and perform operations, I should (haven't tested yet) be able to use
python
to communicate via 1984, and I have rest running on 8984. However, I
cannot
seem to get REST to recognize the existing database.
In my set up, the DB created using basex is at /ats/BaseXData. The
actual
xml files are at /ats/xml/[folders], and my install of basex is at
/ats/basex. Looking at the web.xml, it originally read WEB-INF/Data as
the
dbapth parameter. I have tried /ats/BaseXData, ../../ats/BaseXData, and
other variants without any luck (stopping and starting basexhttp after
each
change). I'm guessing this is more of a jetty question, but I don't
seem to
get anything useful when looking for information on setting absolute
paths
in a web.xml, which is where I think I'm hitting the wall.
Thank you again!

Dear Michael,
sorry for the late feedback. Along with BaseX 7.5, several changes
have been performed in the web application context, so I would like to
hear if you have already tried our latest snapshot [1], and if the
problems are resolved with that version. The new version will be
released pretty soon, which means there will only be minor changes in
the code. If you are running BaseX as web application, the .basex can
be safely ignored.

I have an existing install of basex running on a centos machine. The
install
runs fine, I am able to edit .basex files to point  to the main
database,
and can run the client from anywhere and connect once I make .basex
changes.
I also have jetty6 running (on the same box) with the basex war
package
...
...
(7.3), which also runs, is accessible, and returns valid rest
responses.
My issue is the rest response shows no resources available, which as
far
as
I can tell means it is not connecting to my existing database but
creating
(or created) it's own. Based on the documentation on the site, I have
changed the web.xml's dbpath variable to the existing BaseXData
path. I
have
used the same value I used in the .basex files, repackaged the .war,
and
restarted jetty, with no success.
Other changes, like to the index.html in the war, will show, so I
know I
am
rebuilding the war and viewing those changes correctly.
What do I need to change to make the servlet of basex see a database
folder
already available?
