package main;
 
import org.apache.juli.logging.Log;
import org.apache.juli.logging.LogFactory;
 
public class tomcat {
	public static void main(String[] args) {
		Log log = LogFactory.getLog(tomcat.class);
		log.info("this is a info message from tomcat");
		log.debug("this is a debug message from tomcat");
	}
}

but when debugging tomcat src, I find that org.apache.juli.ClassLoaderLogManager is invoked.

Its entry is in catalina.sh as starting up script for tomcat.
