Subject Re: issues with log4j-web.jar deployed location
Date Wed, 27 Sep 2017 23:35:21 GMT
Matt, remember you can install log4j in tomcat’s lib directory to have tomcat use log4j and
then each web app can also have its own log4j configuration. If the ClassLoaderContextSelector
is working correctly this should work just fine.
