Java Remote Method Invocation (RMI) contains a tool rmiregistry to run a stand-alone remote object registry. According to the RMI tutorial, rmiregistry is normally used in an RMI application. I wonder why. It’s actually almost as simple to run the remote object registry within the RMI server. You only have to use java.rmi.registry.LocateRegistry#createRegistry(int port) method like this: Registry registry = LocateRegistry.createRegistry(port); registry.bind("Foo", stub); Here is a complete example. This is also more efficient since you don’t have to start a separate JVM for the registry.
