How to populate JTable from ResultSet?

I call getnPrintAllData() method after pressing OK button:

public class DatabaseSQLiteConnection {
    Connection conn = null;
    PreparedStatement statement = null;
    ResultSet res = null;
    
    public DatabaseSQLiteConnection(){
        try{
            Class.forName("org.sqlite.JDBC");
            conn = DriverManager.getConnection("jdbc:sqlite:test.sqlite");
            statement = conn.prepareStatement("SELECT * from product_info;");
        }
        catch(Exception e){
            e.printStackTrace();
        }
    }   
    
    public void getnPrintAllData(){
        String name, supplier, id;
        DefaultTableModel dtm = new DefaultTableModel();
        Window gui = new Window(); //My JPanel class        
        try{
            res = statement.executeQuery();
            testResultSet(res);
            ResultSetMetaData meta = res.getMetaData();
            int numberOfColumns = meta.getColumnCount();
            while (res.next())
            {
                Object [] rowData = new Object[numberOfColumns];
                for (int i = 0; i < rowData.length; ++i)
                {
                    rowData[i] = res.getObject(i+1);
                }
                dtm.addRow(rowData);
            }
            gui.jTable1.setModel(dtm);
            dtm.fireTableDataChanged();
            //////////////////////////

        }
        catch(Exception e){
            System.err.println(e);
            e.printStackTrace();
        }
        finally{
            try{
                res.close();
                statement.close();
                conn.close();
            }
            catch(Exception e){
                e.printStackTrace();
            }
        }
    }    
    
    public void testResultSet(ResultSet res){
        try{
            while(res.next()){
                System.out.println("Product ID: "+ res.getInt("product_id"));
                System.out.println("Product name: "+ res.getString("product_name"));
                System.out.println("Supplier: "+ res.getString("supplier"));
            }        
        }
        catch(Exception e){
            e.printStackTrace();
        }
    }
}

testResultSet() method is working properly. How to change my code so that it works, or what is the most simple code to make DefaultTableModel from ResultSet? I am receiving:

java.lang.IllegalStateException: SQLite JDBC: inconsistent internal state

-error.

I think the simplest way to build a model from an instance of ResultSet, could be as follows.

public static void main(String[] args) throws Exception {
    // The Connection is obtained

    ResultSet rs = stmt.executeQuery("select * from product_info");

    // It creates and displays the table
    JTable table = new JTable(buildTableModel(rs));

    // Closes the Connection

    JOptionPane.showMessageDialog(null, new JScrollPane(table));

}

The method buildTableModel:

public static DefaultTableModel buildTableModel(ResultSet rs)
        throws SQLException {

    ResultSetMetaData metaData = rs.getMetaData();

    // names of columns
    Vector<String> columnNames = new Vector<String>();
    int columnCount = metaData.getColumnCount();
    for (int column = 1; column <= columnCount; column++) {
        columnNames.add(metaData.getColumnName(column));
    }

    // data of the table
    Vector<Vector<Object>> data = new Vector<Vector<Object>>();
    while (rs.next()) {
        Vector<Object> vector = new Vector<Object>();
        for (int columnIndex = 1; columnIndex <= columnCount; columnIndex++) {
            vector.add(rs.getObject(columnIndex));
        }
        data.add(vector);
    }

    return new DefaultTableModel(data, columnNames);

}

UPDATE

Do you like to use javax.swing.SwingWorker? Do you like to use the try-with-resources statement?

public class GUI extends JFrame {

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                new GUI().setVisible(true);
            }
        });
    }

    private final JButton button;
    private final JTable table;
    private final DefaultTableModel tableModel = new DefaultTableModel();

    public GUI() throws HeadlessException {

        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

        table = new JTable(tableModel);
        add(new JScrollPane(table), BorderLayout.CENTER);

        button = new JButton("Load Data");
        button.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                new SwingWorker<Void, Void>() {
                    @Override
                    protected Void doInBackground() throws Exception {
                        loadData();
                        return null;
                    }
                }.execute();
            }
        });
        add(button, BorderLayout.PAGE_START);

        setSize(640, 480);
    }

    private void loadData() {
        LOG.info("START loadData method");

        button.setEnabled(false);

        try (Connection conn = DriverManager.getConnection(url, usr, pwd);
                Statement stmt = conn.createStatement()) {

            ResultSet rs = stmt.executeQuery("select * from customer");
            ResultSetMetaData metaData = rs.getMetaData();

            // Names of columns
            Vector<String> columnNames = new Vector<String>();
            int columnCount = metaData.getColumnCount();
            for (int i = 1; i <= columnCount; i++) {
                columnNames.add(metaData.getColumnName(i));
            }

            // Data of the table
            Vector<Vector<Object>> data = new Vector<Vector<Object>>();
            while (rs.next()) {
                Vector<Object> vector = new Vector<Object>();
                for (int i = 1; i <= columnCount; i++) {
                    vector.add(rs.getObject(i));
                }
                data.add(vector);
            }

            tableModel.setDataVector(data, columnNames);
        } catch (Exception e) {
            LOG.log(Level.SEVERE, "Exception in Load Data", e);
        }
        button.setEnabled(true);

        LOG.info("END loadData method");
    }

}
