Can anyone point me at information on the ${} notation used throught the JBAS5.1 deployment configuration files? Example: jgroups-channelfactory-stacks.xml mcast_port="${jboss.jgroups.udp_async.mcast_port:45689}" So where do I specify a value for jboss.jgroups.udp_async.mcast_port to override the default value?
