Like most web servers, Apache Tomcat allows you to configure logging settings for the main web server and the java applications. Using apache logs, you can monitor how the server and your applications are running. Tomcat uses a customized implementation of the JULI (Java Utility Logging Implementation) provided in the java., and util., and logging package.

You should be wondering “What kind of logging does Apache Tomcat use?”
The internal logging for Apache Tomcat uses JULI, a packaged renamed fork of Apache Commons Logging that, by default, is hard-coded to use the java., and util., and logging framework. This ensures that Tomcat’s internal logging and any web application logging will remain independent, even if a web application uses Apache Commons Logging.

You may need to do something similar on other containers if they skip scanning Log4j JAR files. The Log4j 2 Web JAR file is a web-fragment configured to order before any other web fragments in your application.
Because of that, the web applications and libraries using Apache Commons Logging library are likely to automatically choose log4j as the underlying logging implementation., and the java., and util. Logging API is still available for those web applications that use it directly.
