==Introduction== <!--T:1-->
We will see how to authorize a Tomcat9 webapp under Debian to read and write in a folder.
Because under Debian the system rights are not enough for Tomcat, it is indeed put in "sandbox" mode by Systemd and has only write access to the :

    - /var/lib/tomcat9/conf/Catalina
    - /var/lib/tomcat9/logs 
    - /var/lib/tomcat9/webapps
    - /var/lib/tomcat9/work 


==Course== <!--T:2-->
To override this security, you have to edit the Tomcat9 configuration file of Systemd '''/etc/systemd/system/multi-user.target.wants/tomcat9.service''', configuration file, then in the :
<pre>
[Service]
</pre>

Add, to for example allow access to the directory ''/data/'' :
<pre>
ReadWritePaths=/data/
</pre>

Once the modification is done, you have to reload the Systemd daemon:
<pre>
# systemctl daemon-reload
</pre>

Then restart Tomcat9 :
<pre>
# service tomcat9 restart
</pre>
