e504. Defining and Exporting a Portable Remote Object

1. Define the remote interface.

    import java.rmi.*;
    
    public interface RObject extends Remote {
        void aMethod() throws RemoteException;
    }

2. Define the portable remote object implementation.

    import java.rmi.*;
    import java.rmi.server.UnicastRemoteObject;
    
    public class RObjectImpl extends UnicastRemoteObject implements RObject {
        public RObjectImpl() throws RemoteException {
            super();
        }
        // All remote methods must throw RemoteException
        public void aMethod() throws RemoteException {
        }
    }

3. Compile the remote object implementation.

    > javac RObject.java RObjectImpl.java

4. Generate the skeletons and stubs.

    
Using RMI over IIOP
    > rmic -iiop RObjectImpl
    
    Using RMI over JRMP
    > rmic RObjectImpl

5. Create an instance of the remote object and bind it to a name service.

    import javax.naming.*;
    import java.rmi.RemoteException;
    
    
    // JRMP: name = "rmi://localhost/RObjectServer";
    // IIOP: name = "iiop://localhost/RObjectServer";
    try {
        RObject robj = new RObjectImpl();
        new InitialContext().bind(name, robj);
    } catch (NamingException e) {
    } catch (RemoteException e) {
    }
