Using log4j for logging
Greetings,
I wanted to setup log4j for tomcat logs and google searches seems to
indicate that this is possible. Many articles speak about downloading
tomcat-juli-adapters.jar from bin/extras directory.
I found out that for tomcat version 9, extras directory is last present
on version 9.0.14
(https://archive.apache.org/dist/tomcat/tomcat-9/v9.0.14/bin/). Latter
versions do not have extras directory.
Is tomcat-juli-adapters file no longer required? What will be the best
way to configure tomcat logs using log4j.
My main interest is uploading access logs and catalina.out to AWS/S3
bucket. For our application logs, we are already doing this. If there is
a better way to achieve this, open to that solution too.
Regards,
Niranjan

I guess that might work but I'd be surprised.

We are actually using log4j2, I should have been more clearer.
Does this mean we don't have to use specialized juli jar and adapters
and many of the stackoverflow answers are out of date? I have seen
answers saying download juli adapter version from tomcat version 7 and
use it for 9 or similar.

log4j was declared end of life in 2015. If you really need to use log4j
then there are some pointers here:

I'd recommend the answer from Emmanuel Bourg.
If you are using log4j2 then you can use:
