    Default Problem with Jtable with ResultSet

    Hello Everybody:

    im new in this forum and this is my first thread, i hope you can help me, i have a problem with JTable and ResultSetScrollable, the question is that i have a JTable with AbstractTableModel, in the class AbstractTableModel, i override the three methods, getvalueat, getcolumnname....also i have a ComboBox, when i select a value of the ComboBox, the JTable shows the data associated with the ComboBox.

    Well, the problem is that JTable only shows INTEGER data, but String not, i dont know why this could be.

    if someone knows anything about this, would be very grateful.

    this is a part of the code:

    **********This is the AbstractTableModel******************************** *********
    public class PersonalTableModel extends AbstractTableModel{
    ResultSet rs;



    public PersonalTableModel(ResultSet rs) {
    this.rs=rs;

    }

    public Object getValueAt(int ri, int ci) {
    Object ob=null;

    try{

    rs.absolute(ri+1);

    ob=rs.getObject(ci+1);


    }catch(Exception e){
    e.printStackTrace();
    }
    return ob;

    }

    ************************************************** ***********
    ****This is the ItemListener for the ComboBox*******************
    public class ComboCambio implements ItemListener{
    //Recogemos en un objeto tipo ventanaprincipal la ventana principal para acceder a los controles
    VentanaPrincipal ventanaprincipal;

    public ComboCambio(VentanaPrincipal ventana){
    this.ventanaprincipal=ventana;
    }
    public void itemStateChanged(ItemEvent e) {
    PersonalTableModel pt;
    Sql sql=new Sql("BBDDChefDnix");

    Grupo g=(Grupo)ventanaprincipal.combobox.getSelectedItem ();

    pt=new PersonalTableModel(sql.getResultSetScrollable(g.ge tGrupo()));

    //Una vez tenemos el elemento del combobox actualizamos la tabla.

    this.ventanaprincipal.tabla.setModel(pt);

    }

    }
    ************************************************** *

    If you need more code, please tell me and i paste it.

    Thxxxxxxxxxxxxxxxxxxxx a lot!!!

    If you're forever cleaning cobwebs, it's time to get rid of the spiders.
