JTable question regarding Index/ID's from a VB guy

Question

Greets!
So i am coming from VB6 where i use an ActiveX object table to display data from a SQL database table. When populating the table i include the 'ID' field from the database table as a hidden column. So when a user selects a row, i pull the hidden column's ID# and use that to do whatever (bring up another edit form, etc)
So here i am in Java now, i've been playing with jTable for a while now and seem to be getting the hang of the basics, but when i replicated the above scenario, hiding the ID column had weird results (cursor would dissappear when i scroll over with the arrow keys). I also saw another post where another person said that along with populating the jTable i should also have an array that stores the ID that matches the RowIndex from the jTable itself.
This is the table model that i am using:
public class jTableModel extends AbstractTableModel {
    private double xTotal;
    private int colnum;
    private int rownum;
    private String[] colNames;
    private  ArrayList<Object[]> ResultSets;
    private Icon zIcon;
    /** Creates a new instance of FoodTableModel */
    public jTableModel(ResultSet rs,frmMain frm) {
      ResultSets=new ArrayList<Object[]>(); 
      Icon icon1 = new ImageIcon(getClass().getResource("/main/images/bullet_ball_glass_blue.png"));
      Icon icon2 = new ImageIcon(getClass().getResource("/main/images/bullet_ball_glass_red.png"));
      Icon icon3 = new ImageIcon(getClass().getResource("/main/images/bullet_ball_glass_green.png"));
      try{
        while(rs.next()){
            switch (rs.getInt("Type")) {
                case 1: zIcon = icon1; break;
                case 2: zIcon = icon2; break;
                case 3: zIcon = icon3; break;
            Object[] row={zIcon,rs.getString("Name"),rs.getString("Description"),rs.getString("ID")};
            ResultSets.add(row);
        String[] zNames={
            "","Name","Description","ID"
        colNames = zNames;
        colnum=4;
      catch(Exception e){
          System.out.println("(jTableModel: There was an error: " + e);
    public Object getValueAt(int rowindex, int columnindex) {
       Object[] row=ResultSets.get(rowindex);
       return row[columnindex];
    public int getRowCount() {
        return ResultSets.size();
    public int getColumnCount() {
        return colnum;
    @Override
    public String getColumnName(int param) {
       return colNames[param];
    public double getTotal() {
        return xTotal;
    @Override
    public Class getColumnClass(int column) {
     return getValueAt(0, column).getClass();
    }Can anyone give me any tips in this area or point me in the right direction?
Any help would be appreciated.
