The present invention provides a method, system and program product for invoking a remote method. Specifically, the invention provides an interface method object that may be used to map an application interface method call to a remote method call. The interface method object may be generated by retrieving an interface description for the remote method and using the interface description, including any necessary parameters determined from the interface description, to generate the interface method call. The interface method object may be generated dynamically at system runtime. The interface method object facilitates invocation of a remote method by mapping an interface method call from an application in interface method object format to a remote method call in the format of the remote method. Because the interface method call is in an interface method object format, changes to the underlying remote method do not affect the application's interface method call.
