...Review: The Big Picture...
More decisions can be made dynamically
- Service may not be running
- Then connect to an alternate service
- Again using UDDI to discover alternate
- Examining alternate WSDL discovers protocol required is MQSeries
- Then connect to that service using MQSeries protocol instead of HTTP
Notes:
This same program could also make other decisions at run time. For instance, when connecting to the supplier’s service it may notice that this service is not currently running. It could then connect to an alternate company’s service, again by making use of UDDI. It is conceivable that when examining this alternate company’s WSDL it finds that the protocol required to access this new service is MQSeries. Provided that this is acceptable to the requesting program it would then connect to that service, this time using the MQSeries protocol instead of HTTP.
