workers.java_home=/usr/lib/jvm/java-11-openjdk-amd64

ubuntu@tokyoaj:/usr/share$ sudo nano /etc/libapache2-mod-jk/workers.properties

생략

#
# workers.tomcat_home should point to the location where you
# installed tomcat. This is where you have your conf, webapps and lib
# directories.
#
workers.tomcat_home=/usr/share/tomcat9

#
# workers.java_home should point to your Java installation. Normally
# you should have a bin and lib directories beneath it.
#
workers.java_home=/usr/lib/jvm/java-11-openjdk-amd64
#
# You should configure your environment slash... ps=\ on NT and / on UNIX
# and maybe something different elsewhere.
