1031: Highlights

• If you want to run a program on a server computer, then you should use Java's client–server remote-method-invocation mechanism.
• Equip both the client and the server with interfaces that provide signatures for methods to be run on the other side.
• Have the server implement UnicastRemoteObject and a zero-argument constructor that calls super.
• Be sure that all client code to be run on the server is serialized.
• Use the Naming class to bind on the server side and to perform lookup on the client side.
• Compile the client class with the javac command, and compile the server class with the javac command and then the rmic command.
• Start the RMI registry using the rmiregistry command.
• Start the server with the java command. At this point, clients can call methods to be run on the server.
