Installing Tomcat 5 as service

[Cristina]

Hi, I need help about how to install Tomcat 5 as a service shared from
many users. I usually test my application in the modality standalone;
now I need to install Tomcat on a computer of my university lab and to
have an application that I have developed tested (by navigation) by
many users from home.
I read Tomcat documentation but I found it not so clear... can anybody
tell me more simply how to do?

Thanks in advance,

Cristina
