This can usually mean one of two things: 1) Something else is using that port on your machine and you have a conflict. 2)JBoss was not shut down cleanly and this port was never released. 3) You are trying to start multiple JBoss instances on one machine and have not changed your port settings to allow for this. This varies between platforms (Windows, Linux etc). The easiest solution is to do a port scan to determine what above condition applies. Usually port 8080 points to condition two or three. If your on Windows check and see if there is a process called 'java' running. If so, kill it and startup again. Or if you are trying to run two instances shut the other one down and configure JBoss to run multiple instances.
