With apt I've installed the tomcat8 package for Ubuntu Server 18.04.
I've read this Q/A already.
The default path in $CATALINA_HOME is /usr/share/tomcat8/.
There is no folder "webapps". But in /var/lib/tomcat8/ is one.
Both folders have a subfolder lib.
Tomcat's default app is place in /var/lib/tomcat8/webapps.
I've found some nice explanations for the catalina.home vs catalina.base question. But they didn't make it clear to me, how Ubuntu's configuration should be used.
Where should I place my webapps if I use a single instance of Tomcat only?
