Hi Ray
Doesn't look like you are missing anything fundamental to me.
As far as I know the interface CustomerWS should be marked as @Remotable as
binding.ws is a remotable binding. I surfed up that Translator sample that
Ant made and you are right that @Remotable doesn''t appear. Very strange. I
don't know how that worked (assuming it did).
What were the issues you saw when you added @Remotable to the service
interface?
