NET project for this example. Listing 3-2. Main(): Reference to rem. ReadLine(); } } } The sample client will read and output the server’s original value, change it to 42, and then read and output it again. NET REMOTING IN ACTION SingleCall Objects For SingleCall objects the server will create a single object, execute the method, and destroy the object again. SingleCall); Objects of this kind can obviously not hold any state information, as all internal variables will be discarded at the end of the method call.
So a client can ask one server to create an object and safely pass this as a method’s parameter to another server. The second server will then directly execute its methods on the first server, without a round-trip through the client. Nevertheless, this also means there has to be a direct way of communication from the second server to the first one—that is, there must not be a firewall in between, or at least the necessary ports should be opened. NET Remoting application that demonstrates some of the concepts discussed earlier in this chapter.
CreateInstance() or the new operator), an activation message is sent to the server, where an instance of the specified class is created. The server then creates an ObjRef, which is used to uniquely identify this object and returns it to the client. On the client proxy, this ObjRef will be turned into a TransparentProxy, which points to the underlying server-side instance. A client-activated object’s lifetime is managed by the same lifetime service used by SAOs, as shown later in this chapter. CAOs are so-called stateful objects; an instance variable that has been set by the client can be retrieved again and will contain the correct value.
