You’re getting a 404 because ActiveResource doesn’t know how to formulate a URL for your service - it’s going to be trying:
http://localhost:50173/rest_service_impls/1
which obviously won’t work. You’ll either need to figure out how to remap that on the IIS side (surely there’s an equivalent of mod_rewrite) or dig into the ActiveResource docs to tell it how to create the correct URLs.
