[jboss] JBoss default password

I suggest visit Add digest auth in jmx-console and read oficial documentation for Configure admin consoles, you can add more security to your JBoss AS console and at these link explains where are the role and user/pass files that you need to change this information for your server and how you can change them. Also I recommend you quit all consoles that you don't use because they can affect to application server's performance. Also there are others links about securing jmx-console that could help you, search in jboss as community site for them (I can't put them here for my actual reputation,sorry). Never you should has the password in plain text over conf/props/ files.

Sorry for my bad English and I hope my answer be useful for you.
