Abstract

A system and method for enabling firewalled access to a client object residing behind a firewall, via an exported callback reference, by a server object outside the firewall. The system includes callback registry accessible by a proxy operating in conjunction with the firewall. The callback registry proxifies the callback object reference so that a callback will be directed to the proxy which in turn will redirect the callback to the callback object. Callback registry, additionally, stores callback definitions, callback registration and access control policies associated with registered callback objects. These access policies are applied to the callback for the server object to ensure that only authorized objects make the callback on authorized callback objects and their operations.
