Remote Method Invocation (RMI) | Java

You have to build a mobile outlet server based on RMI. Client will generate a call to getPrice(string mobilename) to server class and on server you will get the name of mobile. Create a connection to Database and return the price of that particular mobile to client.
Perform all steps required for complete RMI application.
DB Name: mobile.mdb                              DSN name: mobile

Interface:

import java.rmi.*;
public interface MobileInterface extends Remote
{
double getPrice(String m_name) throws RemoteException;
}

Implementation:

import java.rmi.server.*;
import java.rmi.*;
import java.sql.*;
public class MobileServerImpl extends UnicastRemoteObject implements MobileInterface {
    public MobileServerImpl() throws RemoteException {
    }
    public double getPrice(String m_name) throws RemoteException {
        double price;
        price = Mobilejdbc(m_name);
        return price;
    }
    public double Mobilejdbc(String m_nam) throws RemoteException {
        double p;
        try {
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            Connection cn = DriverManager.getConnection("Jdbc:Odbc:mobileDSN");
            String sql = "Select *from Price where name=?";
            PreparedStatement pSt = cn.prepareStatement(sql);
            pSt.setString(1, m_nam);
            ResultSet rs = pSt.executeQuery();         
            if (rs.next()) {             
                    p = Double.parseDouble(rs.getString(2));
                    return p;
                }       
        } catch (Exception e) {
            System.out.println(e);
        }
        return 0.0;
    }
}

Server:

import java.net.*;

import java.rmi.*;

import java.sql.*;

public class MobileServer 

{

public static void main(String args[])

{

try{

MobileServerImpl obj=new MobileServerImpl();

Naming.rebind("MobileServer",obj);

}catch(Exception e)

{

System.out.println(e);

}

}

Client:

import javax.swing.*;

import java.rmi.*;

public class MobileClient 

{

public static void main(String args[])

{

try{

MobileInterface intobj=(MobileInterface)Naming.lookup("rmi://" + args[0] + "/MobileServer");

String  name=JOptionPane.showInputDialog("Enter Mobile Name:");

double p=intobj.getPrice(name);

System.out.println("Price for mobile: "+name+" is: "+p);

}catch(Exception e)

{

System.out.println(e);}

}

}

Output:
