JBoss does the same basic thing with the java.rmi.server.hostname system property 1) Do nothing if already set (e.g. via -Djava.rmi.server.hostname) 2) else if the -b value isn't 0.0.0.0, set java.rmi.server.hostname to the -b value 3) else set java.rmi.server.hostname to InetAddress.getLocalHost().getHostName() RMI won't work properly if the RMI server isn't listening on the interface specified via java.rmi.server.hostname. For more on this see the https://jira.jboss.org/jira/browse/JBAS-4732 and the forum thread linked from there. In JBoss 4.x, HA-JNDI doesn't expose a config property to let you set it's RMIBindAddress to something other than the -b value. But does setting -Djava.rmi.server.hostname=XXXX let you control the interface that works? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4238849#...
