RMI with JDBC program

Question

i want a program RMI with JDBC code included.

Answer 1

Java RMI programs for implementing Author Registration.
/* File Name : AuthorServerint.java
Java Remote Interface for implementing Author Registration
import java.rmi.*;
public interface AuthorServerint extends java.rmi.Remote
          public void Update_Details(String autid, String name,String
               title,String street, String city, String state, int pin)
               throws java.rmi.RemoteException;
File Name : AuthorServerimpl.java
Java Interface implementation and Server program for implementing
Author Registration
import java.rmi.*;
import java.sql.*;
import javax.swing.*;
public class AuthorServerimpl extends java.rmi.server.UnicastRemoteObject
          implements AuthorServerint
          static Connection con;
          static PreparedStatement ps;
          static ResultSet rs;
          static Statement st;
          int in;
          public AuthorServerimpl() throws java.rmi.RemoteException
               super();
          public static void main(String args[])throws Exception
               try{
                    AuthorServerint As=new AuthorServerimpl();
                    Naming.rebind("rmi://localhost/As",As);
                    System.out.println("Server ready");
          catch(Exception e){
               System.out.println(e);
     public void Update_Details(String autid, String name,String
               title,String street, String city, String state, int pin)
               throws java.rmi.RemoteException
               try{
                    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
                    con=DriverManager.getConnection("Jdbc:Odbc:data");
                    st=con.createStatement();
                    if(autid.equals("") || name.equals("") || title.equals("") ||
                         street.equals("") || city.equals("") || state.equals(""))
                         JOptionPane.showMessageDialog(null,"Fill all the entries");
                    else{
                         in=st.executeUpdate("insert into Author values ('" autid
                              "','"+name+"','"+title+"','"+street+"','"+ city+
                              "','"+state+"','"+pin+"')");
                         if(in>0){          
                              JOptionPane.showMessageDialog(null,"Data Updated");
               catch(Exception e){}
File Name : Authorclient.java

               setVisible(true);
               resize(300,300);
     public void actionPerformed(ActionEvent ae)
               if(ae.getActionCommand().equals("SUBMIT"))
                    try{
                         AuthorServerint A=(AuthorServerint)Naming.lookup ("rmi://
                              localhost/As");
                         autid=tautid.getText();
                         name=tname.getText();
                         title=ttitle.getText();
                         street=tstreet.getText();
                         city=tcity.getText();
                         state=tstate.getText();
                         pin=Integer.parseInt(tpin.getText());
                         A.Update_Details(autid,name,title,street,city,state,pin);
                    catch(Exception E){}
               else if(ae.getActionCommand().equals("EXIT"))
                    System.exit(0);
               else if(ae.getActionCommand().equals("CLEAR"))
                    tautid.setText("");
                    tname.setText("");
                    ttitle.setText("");
                    tstreet.setText("");
                    tcity.setText("");
                    tstate.setText("");
                    tpin.setText("");
     public static void main(String args[])
               new Authorclient();
note: this program is done using swing components and need a database to run. The fields of the table("Author") database("data") are the same as the variable used in "Update_Details" function.
