simplest way to log to tomcat catalina.out

Question

What is the simplest way to write logs to tomcat/catalina.out? I have tried System.out.print() and System.err.print() is working fine.

Answer 1

import java.util.logging.*

Logger.getLogger (YourClass.class.getName()).log(Level.WARNING, e.getMessage(), e);
Logger.getLogger (YourClass.class.getName()).log(Level.INFO, "hello world");
