Debian usage of Tomcat Native Library
=====================================

Enable Tomcat Native Library in Tomcat 8.x:
- edit /etc/tomcat8/server.xml to check if AprLifecycleListener is activated
  [you should remove XML comments if present]
- start or restart Tomcat by using: service tomcat8 restart

Check library loading at Tomcat 8.x startup:
- when starting, Tomcat will output the following log message
  to a file named like /var/log/tomcat8/catalina.*.log
---

If you are using Tomcat 9.x, follow the instructions above, replacing
tomcat8 with tomcat9.
