A system dynamically generates interfaces on demand during runtime execution of an application containing a plurality of objects. A user object generates a request for an interface of a service object. The service object, if the interface is not available, generates an adapter request and transmits same to an adapter manager. The adapter manager selects an interface adapter based on the adapter request from a library of interface adapters or aggregates a composite adapter and transmits the obtained interface adapter to the service object. The service object enables access from the user object based on the received interface adapter.
