Can you translate this file to log4j2.properties style ? Thanks

It could easily be my own error but I think this is no longer valid, possibly due to changes made by Tomcat and log4j in response to the recent log4j2 security issues.

It should have been a no-brainer using the following steps, but it did not work:

• used the latest Tomcat 9 (9.0.56)
• deleted tomcat/conf/logging.properties
• added log4j-api-2.17.1.jar, log4j-core-2.17.1.jar, log4j-appserver-2.17.1.jar to tomcat/lib
• added your log4j2.xml verbatim to tomcat/lib

No log files get created, the Tomcat console shows what looks like original JULI logging.

This worked for me on Tomcat 8.0.30. In addition to these steps also add the disruptor-3.4.4.jar to the $CATALINA_HOME/log4j2/lib folder.
