IdL big time help needed

Question

I have a program and I would like 2 split it into a client-server system using IDL, I would appreciate any tips given (I�m very new to IDL). At the moment it takes input from the user, in the form of a user name and password, and check against a database. I would like to have the input on the client and the check of the database on the server, with eather an accept or refuse message sent back to the user.
import javax.swing.JOptionPane;
import java.sql.*;
public class log
public static void main(String[] args)
//client
String UserId;
String Password;
UserId = JOptionPane.showInputDialog("Eneter your UserID"); // were the user eneters his User
Password = JOptionPane.showInputDialog("Eneter your Password");//were the user eneters his Password
//server
try {
     //have to be in a try catch block
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
//setting up the database
String dataSourceName = "cw2";
String dbURL = "jdbc:odbc:" + dataSourceName;
Connection con = DriverManager.getConnection(dbURL, "","");
//setting up the database
Statement stmt = con.createStatement();
String query = "SELECT Username , password FROM LOG"; // find the values and printen them out
ResultSet rs = stmt.executeQuery(query);
String s, n;
boolean flag = false;
while(rs.next())
s = rs.getString("UserName");
n = rs.getString("password");
if(s.equals(UserId) && n.equals(Password))
flag = true;
System.out.println( " access allowed " );
//grant access
break;
} //if
} //while
if(flag == false)
System.out.println( " access refused " );
//deny access
catch (Exception err) {
System.out.println("ERROR: " + err);
System.exit(0);

You might want to take a look at the examples in
http://java.sun.com/j2se/1.4.1/docs/guide/idl/index.html
and adapt one of the IDL interfaces to your needs.
Something like
module myapp
interface validator
boolean validate_user(in wstring username, in string password);
Note that this won't have any security for your password on the wire.
I just did a quick search to see if I could find a happy IDL tutorial, but I guess I usually use the main CORBA spec, actually.
