Using a loadbalancer fronted cluster and the loadbalancer URL for the WSDL results in ports containing the node URLs instead of the loadbalancer's.
I've tried using the dynamic WSDL rewriting as described in https://docs.jboss.org/author/display/AS71/Advanced+User+Guide but this results in invalid URLs for the ports (with jbossws.undefined.host as the host name and the cluster node port) that haven't been used to access the WSDL, the port used to access the WSDL has the proper address though.
