HOW TO RUN JAVA RMI PROGRAM

 

Remote Method Invocation(RMI) facilitates object function calls between Java Virtual Machines(JVMs)

Step 1

$ first we create interface program like

           /*interface:inte.java*/

import java.rmi.Remote;

import java.rmi.RemoteException;

public interface inte extends Remote

{

        int add(int a,int b)throws RemoteException;

        int sub(int a,int b)throws RemoteException;

        int mul(int a,int b)throws RemoteException;

        int div(int a,int b)throws RemoteException;

}

$ Save the program as inte.java, and compile the program

Step 2

$ Next create a server program like

            /*Server Program:cserver.java*/

import java.io.*;

import java.rmi.*;

import java.rmi.server.*;

import java.rmi.registry.*;

public class cserver extends UnicastRemoteObject implements inte

{

        public cserver()throws RemoteException

        {

                super();

        }

        public int add(int a,int b)throws RemoteException

        {

                return a+b;

        }

        public int sub(int a,int b)throws RemoteException

        {

                return a-b;

        }

        public int mul(int a,int b)throws RemoteException

        {

                return a*b;

        }

        public int div(int a,int b)throws RemoteException

        {

                return a/b;

        }

       

         public static void main(String args[])

        {

        try

        {

                inte c1=new cserver();

                String I="CI";

                Naming.rebind(I,c1);

                System.out.println("Server bound and started");

        }

        catch(Exception e)

        {

                e.printStackTrace();

        }

        }

}

$ Save the program as cserver.java, and compile the program

Step 3

$ Now create a client program like

            /*Client Program:cclient.java*/

import java.rmi.*;

public class cclient

{

public static void main(String args[])

{

        try

        {

        String I="CI";

        inte c=(inte)Naming.lookup(I);

        System.out.println("Ready to continue");

        int i=c.add(2,3);

        int j=c.sub(3,2);

        int k=c.mul(2,4);

        int l=c.div(4,2);

        System.out.println(i);

        System.out.println(j);

        System.out.println(k);

        System.out.println(l);

        }

        catch(Exception e)

        {}

}

}

$ save the program as cclient.java, and compile like

Step 4

C:\java\jdk1.5.0\bin>javac inte.java

C:\java\jdk1.5.0\bin>javac cserver.java

C:\java\jdk1.5.0\bin>javac cclient.java

C:\java\jdk1.5.0\bin>rmic cserver

C:\java\jdk1.5.0\bin>start rmiregistry

// we see the new empty block cmd prompt

//new window

C:\java\jdk1.5.0\bin>java cserver

Server bound and started.

//new window

C:\java\jdk1.5.0\bin>java cclient

Ready to continue
