A system and method for controlling the use by caller objects to a restricted method of a resource object in an object-oriented computing environment are provided in accordance with one embodiment of the invention. The method is based on associating an access-token with a caller object which is to be allowed to access the restricted method and sharing this access-token with the resource object. When subsequent calls to the restricted method are made by a caller object, access is made contingent on the caller object providing the access-token as part of the call procedure. Where no access-token is provided, or an invalid access-token is provided, access to the method is denied or restricted. The method provides protection against innocently made wrong calls to a restricted method by a caller object, for example due to coding errors. The method also provides protection against maliciously made calls to a restricted method by caller objects that should not have access to it.

System and method for controlling the use of a method in an object-oriented computing environment

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.
