    Simple CORBA java server

    This code shows an example of simple corba server in java. A CORBA server needs a local ORB object. The server instantiates an ORB and registers its servant objects so that the ORB can find the server when it receives an invocation for it. the server is a process that instantiates one or more servant objects. Each servant implements the

    Simple RMI Java server

    This code shows a basic RMI server example. A "server" is the class which has a main method that creates an instance of the remote object implementation, exports the remote object and then binds that instance to a name in a RMI registry. Here the server implements the remote interface Hello. The class that contains this main method could be the
    package example.hello;
    	
    import java.rmi.registry.Registry;
    import java.rmi.registry.LocateRegistry;
    import java.rmi.RemoteException;
    import java.rmi.server.UnicastRemoteObject;
    	
    public class Server implements Hello {
    	
        public Server() {}
    
        public String sayHello() {
    	return "Hello, world!";
        }
    	
        public static void main(String args[]) {
    	
    	try {
    	    Server obj = new Server();
    	    Hello stub = (Hello) UnicastRemoteObject.exportObject(obj, 0);
    
    	    // Bind the remote object's stub in the registry
    	    Registry registry = LocateRegistry.getRegistry();
    	    registry.bind("Hello", stub);
    
    	    System.err.println("Server ready");
    	} catch (Exception e) {
    	    System.err.println("Server exception: " + e.toString());
    	    e.printStackTrace();
    	}
        }

    Simple RMI Java client

    This is a simple RMI client implementation. Here the client program obtains a stub for the registry on the server's host, then looks up the remote object's stub by name in the registry. Finally invokes the sayHello method on the remote object using the stub. Here the client invokes the method exposes by Hello remote interface. Note that if no
    package example.hello;
    
    import java.rmi.registry.LocateRegistry;
    import java.rmi.registry.Registry;
    
    public class Client {
    
        private Client() {}
    
        public static void main(String[] args) {
    
    	String host = (args.length < 1) ? null : args[0];
    	try {
    	    Registry registry = LocateRegistry.getRegistry(host);
    	    Hello stub = (Hello) registry.lookup("Hello");
    	    String response = stub.sayHello();
    	    System.out.println("response: " + response);
    	} catch (Exception e) {

    	    e.printStackTrace();
