Now I'm using jboss 7.1 as. Not able access admin console, I already created users and changed standalone.xml also
Thanks in advance.
You should have a look to your logfile, it will show what interface is used to bind port 9990.
Simple is to use the default configuration and start a browser at the same system with localhost:9990
or you start with standalone.sh -b <your IP> and use <your IP>:9990 in your browser
