What version are you running? I pretty regularly run JBoss without an internet connection.
I am using JBOSS 3.2.2 RC3.
Maybe there's something in your machines proxy or network settings then that causes this behavior. Sounds strange.
I have the same version running on my laptop without a problem.
I've the same problem. I keep getting deployment and UnknownHost exceptions while not connected to the internet.
I'm using Jboss 3.2.1.
Does anybody has a solution for this?
