JSP iterator error with structs

Hello there,

I've got some information which is stored in a class object, these objcts are transfered to an action in the format of a set.

I'm trying to put the set into a bean into my JSP, however im not having much luck.

The error is as follows:

org.apache.jasper.JasperException: Cannot create iterator for this collection
The JSP code:

JSP Syntax (Toggle Plain Text) 
  1. <%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %>
  2. <%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %>
  3. <%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic" %>
  4.  
  5. <html>
  6.     <head>
  7.         <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  8.         <title>JSP Page</title>
  9.     </head>
  10.     <body>
  11.  
  12.     <h1>JSP Page</h1>
  13.  
  14.     <jsp:useBean id="address" scope="session" class="Address.AddressForm">
  15.         <logic:iterate id="myIterator" name="address"  type="Address.AddressDTO">
  16.             <bean:write name="myIterator" property="addresses.name"/>
  17.         </logic:iterate>
  18.  
  19.     </jsp:useBean>
  20.     </body>
  21. </html>

My action code: which is invoked before forwarding to this page - it should but the bean into scope:
JSP Syntax (Toggle Plain Text) 
  1. import Data.MyFactory;
  2. imports.........
  3.  
  4. public class AddressAction extends Action {
  5.     public ActionForward execute(
  6.             ActionMapping mapping,
  7.             ActionForm form,
  8.             HttpServletRequest request,
  9.             HttpServletResponse response) throws Exception {
  10.         //Returns a list of accidents and sets accidents attribute in session
  11.         AddressDAO myDAO = MyFactory.getFactory("standard").getDAO(AddressDAO.class);
  12.         request.setAttribute(MMIUtils.addresses,myDAO.retrieveAll());
  13.  
  14.         return mapping.findForward("success");
  15.     }
  16. }
the structs configuration file:

JSP Syntax (Toggle Plain Text) 
  1.   <action
  2.             path="/AddressAction"
  3.             type="Address.AddressAction">
  4.             <forward name="success" path="/success.jsp"/>
  5.         </action> 
  6.     </action-mappings>
and finally the MMIUtils contains this:

JSP Syntax (Toggle Plain Text) 
  1.  static public String addresses = "addresses";

any ideas?
