Hi Sammi, Normal you don't need that sort of logic, but in this case it seems like you do. So your logic below seems correct, I guess you will have a global property that will define which service to use and then each delegate will take care of doing the apppropriate calls. So you can move along with your idea, it should work out just fine. Dimitrios Gianninas Development Team Lead Optimal Payments Inc.

All the webservices supply the same functionality - just in a slightly different way. My idea is this. Use the FactoryPattern for the Delegates. So when a Command needs a delegate it calls the Factory and the factory supplies the command with a delegate. So the command needs a LoginDelegate. It gets a LoginDelegateForWebServiceA(), because the user has previously configured the app to use web service A. I am just so new to actually applying design patterns. I have read many articles and books (Head first Java books are GREAT!) so I understand the concept. I just haven't used it much so I am not sure if my idea is any good. Is this the way to go? Can you point me at any good articles on how to support multiple "backends"?
