Note: I also deployed a simple web module to make sure there isn't security issues with the admin page.
I can access the web module ONLY from the server computer itself
1) I started up a simple EchoServer (a java app with a ServerSocket)that listens on port 8080. It is accessible everywhere.
2)I installed JBoss 4.0.4GA
-- the console is accessible from anywhere on port 8080
Something changed between 4.0.4 and 4.2.1
Thanks for solving my problem!
