Append my application logs to tomcat's ones

Tomcat already has a log displaying information messages like startup ones. I'd like for a servlet of mine to append some custom info to this log.

How to get a tomcat's logger instance from a servlet, so to use it?

System.out and System.err messsages by default written to catalina.out log file, BUT most production systems disable System.out logging to a file.

So the best method to log tomcat's own log files from a servlet is to use javax.servlet.ServletContext.log(...) method. Log messages with this method are handled by internal Tomcat logging.

For more information check the Tomcat Servlet Logging API documentation.

when you write to stdo in ypur servlet, the output redirected to tomcat's log file ./logs/catalina.out. so just use this:

System.out.println("Hello");
