Thanks for all people who replied to my question. I took Emmanuel Bourg's
advice that did the trick. It works!

The tomcat9 package on Debian/Ubuntu uses systemd and leverages its
sandboxing feature to limit the write access to the conf, log, work and
webapps directories by default. If you look at the package's README file
(/usr/share/doc/tomcat9/README.Debian) you'll find the instructions to
grant Tomcat write access to other directories:
https://salsa.debian.org/java-team/tomcat9/blob/master/debian/README.Debian
If write access to other directories is required the service settings
have to be overridden. This is done by creating an override.conf file
in /etc/systemd/system/tomcat9.service.d/ containing:
[Service]
ReadWritePaths=/path/to/the/directory/
The service has to be restarted afterward with:
systemctl daemon-reload
systemctl restart tomcat9
