A method for providing Web services can include the step of registering a Web service with a service provider. The Web service can be installed within a service environment. A request for the Web service can be sent by a service user to an application server disposed within an application environment. The network space of the application environment can be different from the network space of the service environment. The application server can access the requested Web service using a gateway, such as a Parlay gateway. Once the Web service is accessed by the application server, service data for the Web service can be transported between the application server and the service user.
