Are you sure the website is being published on the IP address that you think it is? Are there other IP addresses on this machine?
What do you get if you type in http://127.0.0.1:8080/MovieGalaxy/index.html?
Most probably this is caused by the fact that JBoss (somewhere after 4.0.5) does by default bind only to local network interface (localhost). To make it bind also to other network interfaces you must use the -b command line parameter when starting JBoss (maybe that can also be done by editing some XML, too, but I haven’t used that).
