Point your web browser to http://host:port/commsvc.rest/ControllerService?wsdl, where host is the IP address or host name on which the web container is listening, and port is the port number on which the web container is listening. When you do this, the WSDL file created in the file system during installation is read by the web services infrastructure, and the correct host and port are configured in the WSDL file sent to the browser.
