TOMCAT and 8080 to APACHE. Make sure that these ports are available i.e., no other process
is using this port.
2) Access the above developed static web pages for books web site, using these servers by
putting the web pages developed in week-1 and week-2 in the document root.
3) Access the pages by using the urls: http://localhost:4040/rama/books.html (for Tomcat)
http://localhost:8080/books.html (for Apache)

a). Download Tomcat from the Apache Tomcat site.
b). Execute the downloaded file jakarta-tomcat-5.0.26.zip.
c). Select the "Next >" button.
