US Patent 7992154 Remote method invocation using a server proxy object

A communication device comprises a processor, a server proxy object accessible to the processor, and an object-oriented application that runs on the processor. The application requests a service from the server proxy object. The server proxy object generates a packet that contains an identity of the requested service. The service identity is converted into a corresponding method by a remote computer such that the server proxy object need not change if the corresponding method changes on the remote computer.
