In order to provide some recovery facility, I registered the Weather service with production UDDI registry to enable clients to implement the UDDI invocation pattern (see Chapter 11). To register with UDDI, I saved the service's WSDL, edited it, and removed the implementation part (the <service> element). I saved the resulting WSDL document at http://www.learnxmlws.com/weather/weatherinterface.wsdl. I already had a business entity registered with UDDI so all I had to do was register a new tModel and then register the service itself. The resulting service key is C6DDD2FB-593B-452A-A225-C6A930EFCDE8 and the binding key (which is what you use for the UDDI invocation model) is 400d2ea3-bc66-485d-9594-b3474d801442.
