Abstract
Abstract A system and method that facilitates the development of client applications that wish to request services provided by a Common Object Request Broker Architecture (CORBA) object is presented. Using this system and method, application developers that are developing client applications may, with a familiar web browser, browse and discover currently available CORBA objects registered with the CORBA Naming Service. Similarly for each CORBA object application developers may browse and discover the services provided by that CORBA object as defined by its Interface Definition Language (IDL) interface retrieved from the CORBA Interface Repository. Finally to develop a client application that requests a particular service of a particular CORBA object the application developer may select that service in the web browser view and download an associated proxy that may be quickly and easily integrated with the client application allowing the application developer to develop client applications that use more than one service provided by one or more CORBA objects.
