Although "the same stub may be deployed multiple times", each is a separate
instance and each will be instantiated as part of some client code (running
on server X but web service client code nonetheless). Presumably, the code
doing the stub instantiation knows which endpoint to use and can simply set
it with something like:
locator.setMyServiceSoapEndpointAddress(strEndpointAddress);
I'm obviously missing something here but your scenario, as described thus
far, suggests this as an obvious approach.
