I just found the way to easily refresh a jTable after CRD(not for update) replacing the auto-generated code.

Once you've binded the jTable on your derby table through netbeans designer, all that you need to do is to copy the rebind snippet code autogenerated in the initComponents method.

This is an example that I've copied for my updateJTable method:

    private void updateJTable() {
    departmentList = java.beans.Beans.isDesignTime() ? java.util.Collections.emptyList() : departmentQuery.getResultList();
    org.jdesktop.swingbinding.JTableBinding jTableBinding = org.jdesktop.swingbinding.SwingBindings.createJTableBinding(org.jdesktop.beansbinding.AutoBinding.UpdateStrategy.READ_WRITE, departmentList, departmentT);
    org.jdesktop.swingbinding.JTableBinding.ColumnBinding columnBinding = jTableBinding.addColumnBinding(org.jdesktop.beansbinding.ELProperty.create("${id}"));
    columnBinding.setColumnName("Id");
    columnBinding.setColumnClass(Long.class);
    columnBinding.setEditable(false);
    columnBinding = jTableBinding.addColumnBinding(org.jdesktop.beansbinding.ELProperty.create("${name}"));
    columnBinding.setColumnName("Name");
    columnBinding.setColumnClass(String.class);
    bindingGroup.addBinding(jTableBinding);
    jTableBinding.bind();
    jScrollPane1.setViewportView(departmentT);
}

Meanwhile anyone else will provide us a better elegant solution, this give you an on the fly refresh.
