Abstract
Abstract An improved method and system for transfering remote procedure calls and responses over a computer network is disclosed. The system and method make use of a generic RPC client stub and a generic RPC server stub to replace all the dedicated RPC stubs normally associated with each client and server application. The generic stubs are customized, upon invocation, to transmit and retrieve information or programs across the network as if they were regular stubs.
