I'm sorry for the late answer.
I am testing it on my PC so im using Windows7 64bit.
But wheather im using -b 0.0.0.0 or -b 192.167.1.100 doesn't really matter to me, I leave that yo tou JBOSS gurus I'm happy that now everything is working and hopefully the students will be able to use it next semester.
My only worry is security, our network is not accessable from the outside, but I still want to hide the JBOSS server from port 8080 оr any other port. Isn't there a way to set JBOSS so you can't access the contents visible on 8080 unless u have some pass and a user.
Thank you. :)
