A couple months ago I had no problem configuring Tomcat 9 with java 16
to use log4j2.
That time I simply deleted tomcat/conf/*logging.properties*, added to
*tomcat/lib* the following files and it worked.
* log4j-api-2.*.jar
* log4j-core-2.*.jar
* log4j-appserver-2.*.jar
* log4j2.xml
Now I am setting up a new tomcat 9.0.56 with java 17 and log4j 2.17.1,
followed the same steps with one difference... I tweaked the log4j2.xml
to try to make it cleaner and easier to maintain/adjust.
Unfortunately my new setup is failing to log anything at all. The only
place where I see something is on the console and it looks like it is
not even log4j output as it does not match the pattern I expected. I
think I am misunderstanding something about the use of properties in a
log4j2.xml file or I have some really dumb typo.
I hope someone can give a glance at the following and tell me where I
messed up:
