Why can't the JSP display the data with logic:iterate?

Question

Hi,all
I am writing a web application with Struts framework. I dont know what's the problem when I use the tag logic:iterate in my application. I have created a form bean follow source code:
public class ProductsForm extends ActionForm {
     private Vector alist;
     public void reset(ActionMapping mapping, HttpServletRequest request) {
     this.alist = new Vector();
     public Vector getAlist() {
          return alist;
     public void setAlist(Vector alist) {
          this.alist = alist;
I also created action for the form
public class ProductsAction extends Action {     
public ActionForward execute(
          ActionMapping mapping,
          ActionForm form,
          HttpServletRequest request,
          HttpServletResponse response)
          throws Exception {
               String target = "success";
               if(form!=null){
                    ProductsForm aForm = (ProductsForm) form;
                    Vector aList = new Vector();
     //loadProductsList() method return the Vector object
// which is a array included Product object.
                    aList = loadProductsList();
                    if(!aList.isEmpty()){
                    request.setAttribute("aList",aList);
               return mapping.findForward(target);
JSP page follow:
<logic:iterate id="aitem" name="aList">
<tr>
<bean:write name="aitem" property="productname"/>
</tr>
</logic:iterate>
Anybody tell me why the JSP page can't display the result. Thanks.

Are you getting any error messages, or are you just not seeing anything in the page? If you get error messages, please post them.
