Abstract: Methods for establishing communication between computing entities are provided. In one example, a service model illustrates communication with a web server using a service proxy to manage a communication exchange. The service model includes a dispatcher within the service proxy to process the communication exchange. The processing of the communication exchange includes defining a request, defining a container in which to enclose the request, defining a post request event to dispatch the container with the request, and defining a response container for obtaining a response to the request. The container with the request is transmitted through the web server to a service for a responding entity. The service uses a delegate registry to map the request to a delegate which obtains a response from the responding entity. The response is formatted and transmitted through the web server to the service proxy which provides the response to the requesting entity.
