copy a new HTML page to webapps\ROOT
"C:\tomcat\Tomcat-4-1-18\webapps\ROOT\MyHTMLPage.html"
if you are running locally
the url would be

http://localhost/MyHTMLPage.html
or
http://localhost:8080/MyHTMLPage.html


If for any reason it did not work find where jakarta-banner.gif , and index.jsp
located
that would be the root directory of your tomcat server.
