I've been unable to reproduce your problem with the setup you sent me. I have no problem sending messages. What's in your /etc/hosts file? Mine includes | # Do not remove the following line, or various programs | # that require network functionality will fail. | 127.0.0.1 localhost.localdomain localhost | ::1 localhost6.localdomain6 localhost6 | What params are you passing to run.sh when you start JBoss?
