Ron, to see if it is running, just go to
http://localhost:8080/web-console That is the simplest.
Now here is a caveat, while that will show you that JBoss is running, it does not necessarily mean that everything services and apps got deployed. You could still have an exception in a service that doesn't deploy but still JBoss is running and installed. You have to look at the console and check to see if any exceptions show up.
