Configuring JBoss Server to Access a Host Name is optional and required only to access the JBoss Server using the host name (rather than localhost/127.0.0.1).
This procedure is not used when Preparing Your Environment for JBoss 6.x Integration
Note:
Starting JBoss Server using -b 0.0.0.0 allows the user to access the server using host name rather than localhost / 127.0.0.1. Otherwise, JBoss Server can be accessed using localhost / 127.0.0.1 as well as host name.
