Popolare jTable da DB

[haidi8]

Salve a tutti, come da titolo devo popolare una jTable da DB, il programma che uso è Netbeans.
Come modello di tabella devo usare un AbstractTableModel e non Default (richiesta del prof).
La classe DBTableModel che estende AbstractTablemodel è stata fornita dal prof.
L'errore che mi ritorna, ripetuto varie volte è:
Resultset chiuso: getRow

non riesco proprio a capire perchè mi dia questo errore, mi setta il nome delle colonne in modo corretto, ma le righe non ci sono
Vi posto il codice:

package javaapplication9;

import java.sql.*;
import java.util.logging.Level;
import oracle.jdbc.pool.OracleDataSource;
import javax.swing.*;
import java.sql.Connection;
import javax.swing.table.DefaultTableModel;

public class MioFrame extends javax.swing.JFrame {

    int pos=1;
    Connection conn=null;
    DBTableModel modelTable;

    public MioFrame() {
        initComponents();

        try {
            //Connessione al DB
           OracleDataSource ods = new OracleDataSource();
            ods.setURL("jdbc:oracle:thin:@//localhost:1521/xe");
            ods.setUser("--------");
            ods.setPassword("********");
            conn=ods.getConnection();

 String q="SELECT * FROM  LISTADESIDERI WHERE ID_CLIENTE = ? ";
 PreparedStatement stAccess =conn.prepareStatement (q, ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);

 stAccess.setString(1,"1234567890");//con questo id sono sicura che ci sono dei dati
     
          //eseguo la query
          ResultSet rset=stAccess.executeQuery();

         modelTable = new DBTableModel(rset);
         jTable1.setModel(modelTable);
         modelTable.setRS(rset);
          
            rset.close();
          
        }catch (SQLException ex) {
       Logger.getLogger(MioFrame.class.getName()).log(Level.SEVERE, null, ex);
           }        
  }
