Is it a good idea to install the Tomcat module in WHM?

Please share your experience and include your specs:
O/S
Server Specs
Estimate number of clients on server

Also, is Tomcat specifically for Java applets or java scripts? What's the difference (newbie lol). Is "servlets" for java specifically?

Thank you.

What exactly is WHM? I've never seen that term.

cpanel / whm (web host manager)

Yes, Tomcat is a servlet container. It handles servlets and Java server pages. Servlets are kind of like CGI scripts, but better (or so the Java people claim) because they always stay resident within the Java Virtual machine, whereas CGI scripts are completed reloaded (the WWW server forks and execs them) each time they are called. Therefore you can maintain persisten state and do other such tricks. Tomcat's relatively easy to manage, and I've played with it a bit, but if you don't know a little bit of Java, it might be somewhat of a slog.
