A standard Tomcat installation starts the webserver on port 8080 – which is usually not the desired behavior. In order to change the server to port 80 there are two options which I outline in the following:

I just installed Tomcat 7 on my Windows machine and tried to fire it up through Netbeans. But instead of a running server, I just got an error message that command 127.0.0.1 could not be found (Localized error message: Der Befehl “127.0.0.1” ist entweder falsch geschrieben oder konnte nicht gefunden werden.).
