Error in row problem using rs.deleteRow()

Question

I am new to JCDB and can not figure out why this code does not work. Can somebody please help?
import java.applet.*;
import java.lang.*;
import java.applet.Applet;
import java.util.Date;
import java.sql.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class p1 {
public static void main(String args[]) {
Connection con=null;
Statement stmt=null;
ResultSet rs=null;
String url;
try {
String filename = "U:/profile.cu/Desktop/Java Book_DB/db1.mdb";
url = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=";
url+= filename.trim() + ";DriverID=22;READONLY=true}";
String user = "";
String pwd = "";
// Using the direct way to connect to the database
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver" );
con = DriverManager.getConnection( url, user, pwd );
stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE );
String Password, Date, Email ;
rs = stmt.executeQuery("SELECT * FROM Users");
while ( rs.next() ) {
Date = rs.getString("date_last_used");
Password = rs.getString("password");
Email = rs.getString("email_address");
System.out.println( Password+ " " + Date + " " + Email + " ");
     //int rowNumber = rs.getRow();
//rs.absolute(rowNumber);
rs.deleteRow(); //THIS IS WHERE PROBLEM IS!
//con.commit ();
     //rs.updateRow();
}// while
/* rs = stmt.executeQuery("SELECT Date FROM Users");
rs.absolute(1);
rs.deleteRow(); // THIS ALSO DOES NOT WORK
rs.updateRow();
// Close the statement
stmt.close();
// Close the connection
con.close();
System.out.println("Finished");
} //try
catch ( ClassNotFoundException cnfex ) {
cnfex.printStackTrace();
catch ( SQLException sqlex ) {
sqlex.printStackTrace();
catch ( Exception ex ) {
ex.printStackTrace();
} // main
} // p1
This is the error that I get:
java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver]Error in row
at sun.jdbc.odbc.JdbcOdbcResultSet.setPos(JdbcOdbcResultSet.java:5275)
at sun.jdbc.odbc.JdbcOdbcResultSet.deleteRow(JdbcOdbcResultSet.java:4204
What in the world is wrong. I tried everything and read a lot and could not solve the problem.

Hi
Why don't you use the DSN in Windows to create the url to the db. Go to ODBC Data Source Administrator (in win2000 its in Control Panel) then create a DSN name (e.g. yourdb), select the Microsoft Access driver, give it a name & point it to the database file.
Then you connect using the code below
String url = "jdbc:odbc:yourdb";
Connection con = DriverManager.getConnection(url);
Staement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE );
This should work when deleting, good luck
ps. perhaps the reason it doesn't work before is coz you set READONLY=true when you create the url :)
