Using Arrays Problem

[Paola Orsini L]

Hi I having problems in getting back the values of the users.
I have a shopping cart that display and I have an array with the quantities, to be display and can be edited by the user, I can display the content but I can not get the values enter for the user, can anyone help.

ProductsForm:

 
private List<Productos>  productsList;   
private String[] quant ;

public String getQuant(int index) {
        return quant[index];
}
public void setQuant(int index, String value) {
        this.quant[index] = value;
}
public String[] getQuant() {
        return quant;
}
public void setQuant(String[] quant) {
       this.quant = quant;
}
public List<Productos> getProductsList() {
       return productsList;
}
public void setProductsList(List<Productos> productsList) {
       this.productsList = productsList;
}

Action to set the values

    

public ActionForward open(ActionMapping mapping, ActionForm form,
	HttpServletRequest request, HttpServletResponse response)			
{
	ProductsForm productsForm = (ProductsForm)form;
	Session sess = HibernateSessionFactory.getSession();
	long cod = Long.parseLong(request.getParameter("COD"));
	List<Productos> prod = Productos.getAllForAttribute(sess,ID_GROUP, cod);
	productsForm.setProductsList(prod);
	String[] q = new String[prod.size()];
	for(int i=0; i<prod.size();i++)
	{
	       q[i]=Integer.toString(i+1);
	}
	productsForm.setQuant(q);
									
	sess.close();
	return mapping.findForward(SUCCESS);
}

in the jsp:

    
<logic:iterate name="products_form" property="productsList" indexId="index" id="productos" >
      <tr>
      <td><table cellpadding=1 cellspacing=1>
             <tr><td colspan=3>
	    <bean:write  name="productos" property="titulo" />				
             </td></tr>
             <tr><td>
	     Bsf. <input style="border: 0" id="precio_<%=index+1 %>" name="precio_<%=index+1 %>" type="text" value='<bean:write  name="productos" property="costo" />'>						  
             </td>
             <td>cant <input name="cant"  type="text" size="3" value="0"  onkeyup="sumar();"/> 
	<html:text styleId='<%="quant["+index+"]" %>' name="products_form" property='<%="quant["+index+"]" %>'/>
             </td>
              </tr></table>
             </td></tr>
</logic:iterate>

So I hava a javascript function that change the value of quant[] each time the value cant has change but when I sumit the form i can not retrieve this values, even I tried without the javascript and its the same

I have session scope in my struts-config.xml action
