Where is the jboss.bind.address configured?

jboss.bind.address is configured using the "-b" option to the JBoss startup script (run.sh or run.bat in the bin directory).  For example, run -b 0.0.0.0 enables jboss to listen for connections on all IP addresses of the machine (if multi-homed). 

Where is the -b option documented?

The -b option is documented here: JBossRunParameters.
