The Tenuki wrapper uses a configuration file to govern how the application is launched. To add the '-b 0.0.0.0' boot option to the JBossAS, add the following properties to the configuration file:
You should already have "wrapper.app.parameter.1=org.jboss.Main" in the configuration file. If you already have some other parameters declared, you will have to adjust the parameter numbers.
That was the part I was missing. Works fine now!
