We have a very old ubuntu box (8.04) that is running basically to have one site running on apache2 http server.

Now I need to have something run on a j2ee application server (tomcat).

How will it influence the apache2 installation (and everything running on it) if I install tomcat (via apt)?

Will it auto configure tomcat to run on a different port or do I need to do something manually.

How do I install tomcat without disrupting the apache2 server and everything running on it?
