By the "multi-home" limitation do you mean configuring the bind address in the JGroups UDP protocol? That's pretty straightforward. You can control the interface JGroups uses by setting system property -Djgroups.bind_addr=192.**** as a command line argument. If don't specifically set jgroups.bind_addr and you use -b, JBoss will set jgroups.bind_addr to the -b value. Except... if you use -b 0.0.0.0, a value JGroups can't use. In that case, JBoss will set jgroups.bind_addr to the value of InetAddress.getLocalHost().getHostName(). None of the above is directly relevant to HA-JNDI. I'm checking if your HA-JNDI problem results from your use of -b 0.0.0.0 though. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4238847#...
