127.0.0.1 is the "loopback" address, which is kind of a shortcut for addressing the originating machine. localhost is generally configured to point to 127.0.0.1, but you could theoretically change that to something else in yours hosts file (although that wouldn't be a good idea).
8080 happens to be the default port that Tomcat attaches itself to. That can be changed to something else in the startup scripts if you want.
