If you look at the jboss-service.xml mbean where you set ports-01, etc, there's a "StoreURL" attribute: | <mbean code="org.jboss.services.binding.ServiceBindingManager" | name="jboss.system:service=ServiceBindingManager"> | <attribute name="ServerName">ports-01</attribute> | <attribute name="StoreURL">${jboss.home.url}/docs/examples/binding-manager/sample-bindings.xml</attribute> | <attribute name="StoreFactoryClassName"> | org.jboss.services.binding.XMLServicesStoreFactory | </attribute> | </mbean> That tells you the location under the root of your JBoss install where it finds the file it uses to alter the ports. You can look at that file to see what it is doing. You'll have to think about/interpret it, as it isn't documentation.
