PORMI Question - Where do clients get a definition for remote classes that have not been added to registry?
text
Body
copied!<p>Ive managed to create an RMI application that does what i need it to do quite succesfully, but im having a bit of trouble getting my head around where client obtains definitions for remote objects. for example:</p> <p>I have a server that registers itself with the rmiregistry (allowing clients to call methods on it).</p> <p><code>UnicastRemoteObject.exportObject(new Server(), 0);</code></p> <p>running <code>reg.list()</code> confirms that my server has indeed been added to the registry. I have another remote object (rObj) running on the same JVM as the server. This is not added to the registry. </p> <p>In my client, i can get the definition of my Server class by looking up <code>Server</code> in the rmiregistry:</p> <p><code>reg.lookup("Server")</code></p> <p>after this can freely create instances of rObj. The crux of my question is, where does my client get a definition for rObj even though its never been added to registry.</p> <p>I know it must come from the server as thats where the class and interface are stored. Does the connection to <code>Server</code> automatically open the pipe for other remote classes to received? </p> <p>If so, how does the client know to look on the server for the remote class. Is the server treated almost as an extension to the clients classpath (it will resort to checking the server for classes that arent in its own classpath)?</p>
