Dropdown list error - in table

Question

Hi,
I�m trying to make a table with different fields, with one database. For example:
Name product Number of products
So i want to put in the number of products�s a dropdown list. For example, if the product chocolate has 6 units, in the dropdowlist may appear 1-2-...6 and i will select what i want. The database has a field withs these fields.
So, what i have done is this:
private void vinos(){
   int noofDBRows = vinosDataProvider.getRowCount();
   listOptionsVinos = new Option[noofDBRows + 1];
   int rowcount = 0;
   if (noofDBRows > 0) {
       // Build the Options Array with the data
       // from DataProvider plus Dummy Value
      vinosDataProvider.cursorFirst();
      do{
          String linea=vinosDataProvider.getCursorRow().getRowId(); 
          int aux=Integer.parseInt(vinosDataProvider.getValue("nUds").toString());
       for (int i=0;i<aux;i++){
            String i2=String.valueOf(i);
           listOptionsVinos=new Option(i2);
} while (vinosDataProvider.cursorNext());
// Add Dummy Value to Array at the end,
// Use Dummy Value ("999") as Value for the Dummy!!
// Note : - You could add the Dummy value at
// any position of your choice
listOptionsVinos[rowcount] = new Option("999", "-------");
} else {
listOptionsVinos[rowcount] = new Option("999", "No Rows from DB");
} public void init() {
vinos();
}I have based in this page:
http://www.netbeans.org/kb/55/dropdowncomp.html
I know that it is erroneous because the listOptionVinos is common for all the rows, so if anyone could help me i will be pleased.
Thanks you very much!

Answer 1

Hi, again!
The two columns are from the same table, yes. Here is an example of the database:
Name number
chocolate 3
In the db only appear the number 3, so what i want is that in the dropdown appear numbers from 0 to N, in this case 3. So i will choose the number what i want. To do this, i have done a function in mysql which functionalitty is to return numbers from 0 to N. So if i send the number 3, it must send numbers from 0 to 3.
After that, to prove it, I have created a new one dropdown sending a random value to the procedure. But when i run it, the dropdown doesn`t show anything. This is the code that i have done:
public SessionBean1() {
public void init() {
        a3();
public void a3(){
        try{
            String num="3";
            cantidadRowSet.setCommand("CALL sp_NumberList(?)");
            cantidadRowSet.setObject(0,num);
           cantidadDataProvider.refresh();
           int noofDBRows = cantidadDataProvider.getRowCount();
          opcionesprueba2 = new Option[noofDBRows+1];
           int rowcount = 0;
           if (noofDBRows > 0) { 
            cantidadDataProvider.cursorFirst();
           do {
           opcionesprueba2[rowcount] = new Option(cantidadDataProvider.getValue("1").toString());
           rowcount++;
            while (cantidadDataProvider.cursorNext());
            opcionesprueba2[rowcount] = new Option("999", "---------");
            }else{
        opcionesprueba2[rowcount] = new Option("999", "No Rows from DB");
        }catch(SQLException e){}
   }Thank you very much
