I tried setting up ServiceBindingManager according to the wiki: http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfiguringMultipleJBossInstance... I find that when I start up the FIRST instance, I get an error telling me that port 4446 is already in use. The wiki says: anonymous wrote : AS 4.0.2 has a known bug : one of the ports (4446) is not included in the sample-bindings.xml file and therefore will continue to conflict even after selecting an alternate port configuration in your jboss-service.xml. To fix this simply select an alternate port (something other than 4446 that is not being used) in cluster-service.xml configuration (obviously not necessary if you are not using the ALL configuration with clustering support). This bug is being fixed in our next release. I came across this on a pristine box which had never seen another version of JBoss. Apologies, don't have the log file with me now (posting from home, not work); have probably already lost the file... Just thought someone might like to know...
