java.lang.Objectcom.jproxy.proxy.callback.HttpCallbackServer
The implementation of remote object used to support callback This object is shared between several callers and one consumer. The callers an consumer are remote objects also. For each client that uses callbacks one instance of the class exists on the server. The remote object provides temporary storage for requests to be done on the client. All requests to perform callback on the client are stacked in the object. The client contacts the object in order to get the requests and then performs them in original order.
