RMI-Example-1
This is a very simple example of RMI where you will come to know how RMI
works and what are the steps of executions. Here listed four java files and
steps for executing this application.
Code:
RemoteInterface.java
import java.rmi.*;
public interface RemoteInterface extends Remote
{
public int add(int x,int y)throws Exception;
}
|
ServerImplements.java
import java.rmi.*;
import java.rmi.server.*;
import java.lang.String;
interface RemoteInterface extends Remote
{
public int add(int x,int y)throws Exception;
}
public class ServerImplements extends
UnicastRemoteObject implements RemoteInterface
{
public ServerImplements()throws Exception
{
super();
}
public int add(int x,int y)
{
return (x+y);
}
}
|
Server.java
import java.rmi.*;
import java.net.*;
public class Server
{
public static void main(String args[])
{
try
{
ServerImplements s=new ServerImplements();
Naming.rebind("SERVICE",s);
System.out.println("Server Started ");
}
catch(Exception e)
{
System.out.println(e.getMessage());
}
}
}
|
Client.java
import java.rmi.*;
import java.io.*;
public class Client
{
public static void main(String args[])
{
try
{
String ip="rmi://192.168.1.97/RMIAPPLICATION";
RemoteInterface s=
(RemoteInterface)Naming.lookup(ip);
System.out.println("sum: "+ s.add(1,3));
}
catch(Exception e)
{
System.out.println(e.getMessage());
e.printStackTrace();
}
}
}
|
Steps for executions
javac RemoteInterface.java
javac ServerImplements.java
rmic ServerImplements
javac Server.java
javac Client.java
start rmiregistry
start java server
java Client
Output:
Sum: 4
