using ResultSet.Previous method not working in Java using .mdb file OBDC

I'm currently having an issue with my open result set not working how I believe it should. The only function that is currently working is the next() method, nothing else will work. If the project is placed into a debug mode you can follow through actionperformed event on the button it hits the previous() method and jumps over the remaining code in the method. If someone could point me in the right direction it would be truly appreciated.

FORM CODE:

import java.sql.*;
import javax.swing.*;

public class DataNavigator extends javax.swing.JFrame {

public DataInterface db = null;
public Statement s = null;
public Connection con = null;
public PreparedStatement stmt = null;
public ResultSet rs = null;

/** Creates new form DataNavigator */
public DataNavigator() {
    initComponents();

    try {
        db = new DataInterface("jdbc:odbc:CMPS422");
        con = db.getConnection();
        stmt = con.prepareStatement("SELECT * FROM Products");
        rs = stmt.executeQuery();
        rs.last();
    } catch (Exception e) {
    }
}

On the statement you have to set the ResultSet Type to be TYPE_SCROLL_INSENSITIVE. see the tutorial.
