How to configure Tomcat 6.0.20?

[Varuna Seneviratna]

I want to set the below settings in Tomcat 6.0.20

How to change the port from 8080 to 80?
How set the DefaultReloadable attribute to true?
How to set the <Context path="" docBase="ROOT" debug="0" />
How to turn on the invoker servlet?

All the above changes were instructed to be made in the Book Core Servlets and JavaServer Pages second Edition by Marty Hall and Larry Brown
I am not able to find the mentioned landmarks in order to make the desired changes since the version of Tomcat is changed

Examine the server.xml file for the configuration information - also your Tomcat distribution contains a whole bunch of detailed information in html files.

I strongly advise that you not use the invoker servlet. That book is 6 years out of date.
