[jboss-dev-forums] [Design of Clustering on JBoss (Clusters/JBoss)] - System property expansion with Multiplexer

[bstansberry@jboss.com]

One multiplexer integration problem I've noticed is using the JBoss system property expansion technique doesn't work with multiplexer-stacks.xml.  E.g. 
<UDP
  |              mcast_port="45588"
  |              mcast_addr="${jboss.partition.udpGroup:228.1.2.3}"...v will fail on setting up the protocol stack.

Haven't thought about it; perhaps the solution is trivial.


On a tangential topic, if we can solve the above problem, one good thing the multiplexer provides is the ability to set the multicast port via a system property and/or startup switch.  That will make life easier for admins needing to segregate clusters.  Wasn't practical before due to the numerous Channels deployed in a server.
