Hi Mark, Just a little bit more on late-binding. I've just found in http://lists.w3.org/Archives/Public/www-ws-arch/2002Jun/0243.html this : " Dynamic Binding - The WSDL PortType is not known or set at development time. Neither is the location. The service requestor is repsonsible for finding a service it wants to use, introspecting the portType and invoking it using a DII or a runtime generated Stub or Proxy. (scenario: Hospital doesn't do contracts with vendors and always polls a set of vendors for best available price on gloves. If there are no standard PortTypes for price quotes and ordering gloves, the softward could introspect a variety of WSDLs looking for a certain message signature or variations of a message signature it can recognize as a getPrice or orderGloves operation. Since we don't have many (or ANY!) stardized PortTypes yet.... you can see how this has to happen. )" The following message says that a standard message format is necessary, but it doesn't seem to be strictly required. I guess it answers my question on a possible programming model for a client who accesses late-bound services. As far as an application is concerned, there could be several modules, one processing late-bound soap-services, another one - late-bound xml services, etc Then the output from all of them is routed to a normalizer, etc Any comments ? Cheers Sergey I guess
