I have installed Apache tomcat 5.5 as a service in my system. Also i added a custom logging file using log4j for a web application. whenever i used system.out.println(\"some tex
When started as a service, you can configure the file locations for the stdout and stderr messages from the Service Manager.
Though I agree with @Brabster, you should be using log4j logging instead of System.out when you want to move into production.
