-> I asked where the jars are located. You replied "Along with various other product libs, log4j2 jars and log4j2 propertie file are placed under soa-dir/lib. This path is accessible by all 3 wars.” That answer implies that they are not in WEB-INF/lib of any of the web apps.
We needed log4j2 jars in soa-dir/lib since these log4j jars are required by one more process other than my webapps wars process. My webapps war doesn't contain log4j*.jar. However other 2 jars are being fetched from artifactory and those wars already contain log4j2 jars. -> Second, putting the property in log4j2.component.properties is correct. However, it must only be on the classpath of the web app that needs it, not in a shared directory. This could not fix the issue earlier, I would try again putting it various places in webapps war file. -----Original Message----- From: Ralph Goers <ralph.go...@dslextreme.com> Sent: Thursday, April 7, 2022 11:21 AM To: Log4J Users List <log4j-user@logging.apache.org> Subject: Re: can we set log4j property 'Log4jContextSelector' per webapps war *** External email: Verify sender before opening attachments or links *** I asked where the jars are located.

First, I do not know why you are still using a custom Logger since we already advised you not to do that. Second, putting the property in log4j2.component.properties is correct.
