Check the SourceForge JBoss site and look through the Buglist. It may have been a configuration file bug (there were a few) in the JBoss 3.2.1 release. You could also check the 3.2.2RC3 to see if the configuration file has been changed. If it still exists, and there is no bug report, you can log the bug there.
Added bug # 800923 on SourceForge.net
Does anyone know what the DOCTYPE format should be for user-defined instances of jboss-service.xml? I understand that 3.2.2 requires this now.
