Yes, it is critical to know the JNDI port to help shut JBossAS down. If I recall correctly, some older versions of JBossAS used to log the JNDI port to the console log, but the more recent versions do not appear to do that. Knowing the JNDI port is somewhat crucial. Wonder if there is an MBean that has that info? Yes there is: jboss:service=Naming, the Port attribute. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4160954#...
