insert Row into jtable using AbstractTableModel with hibernate

im developing an application and i'm trying to insert a new row into jtable i've followed this tutorial , the user can add/remove product information(row) through a form.the database & the table should be updated ,the remove function works well but i can't insert new row into the table . Note:- when i close the app & run it again the table is updated and here's my code

public class TableModel extends AbstractTableModel {

Object[] values;
String[] columnNames;
private ArrayList productInfoList;

public TableModel() {
    super();
    Session session = HibernateUtil.openSession();
    Query q = session.createQuery("from Product");
    productInfoList = new ArrayList(q.list());

    session.close();
}

@Override
    public int getRowCount() {
   //return dataVec.size();
     return productInfoList.size();
}

@Override
    public int getColumnCount() {
    return 9;
}

@Override
    public Object getValueAt(int rowIndex, int columnIndex) {
    Product product = (Product) productInfoList.get(rowIndex);
        values = new Object[]{product.getProdectId(),
        product.getProductName(), product.getProductBuyingPrice(),
        product.getProductSalesPrice(), product.getCategory(), product.getBrand(), 
        product.getProductQuantity(), product.getProductMinQuantity(), product.getProductDescription()};

    return values[columnIndex];

}
@Override
    public String getColumnName(int column)
{
    columnNames=new String[]{"id","Product Name","Buy price","Sale price ","Category",
    "Brand","Quantatity","Min Quantatity","Description"};
    return columnNames[column];
}
public void removeRow(int rowIndex) {
    productInfoList.remove(rowIndex);
    fireTableRowsDeleted(rowIndex, rowIndex);
}

public void insertRow(int rowIndex,Product everyRow) {
    productInfoList.add(rowIndex, everyRow);
    fireTableRowsInserted(rowIndex, rowIndex);
}
  }

this is the code that i try to insert row with 

public void AddRow() {
    int position = jTable1.getRowCount() - 1;
    System.out.println(position); // test
    Product product = new Product();
    tablemodel.insertRow(position, product);

}

Please help me as i'm get tired of it :|

Your TableModel is storing a Product object in an ArrayList.

So, when you want to add a new row to the model you need to create a new Product object and add the Product to the ArrayList.

Also, you don't need to invoke table.repaint(), the insertRow(...) method is invoking the fireTableRowsInserted(...) method which will tell the table to repaint the row.
