 Hi all,I know that my question is common, but I�m still struggling with the iterate tag.Please can somebody help me?When I�m using the logic:iterate tag I get only the following error:
"javax.servlet.ServletException: Cannot create iterator for this collection"

The not working code is: <jsp:useBean id="myUser" scope="session" class="com.aspo.Model.User"/>
<logic:iterate id="profile" name="myUser" property="userProfiles">
<tr>
    <td align="left">
      <bean:write name="profile" property="name" filter="true"/>
    </td></tr>
</logic:iterate>
************************************************************************************
The same iteration works with this code:<%
ListIterator profileIterator = myUser.getUserProfiles().findAll();
while (profileIterator != null && profileIterator.hasNext()) {
UserProfile profile = (UserProfile) profileIterator.next();
%>
<tr><td width="330px"><a class="list" href="editProfile.do?action=Edit"><%= profile.getName() %></a></td>
</tr>
<%}%>Can anybody tell me what I'mdoing wrong?
Thanks,Katarina

What kind of object does the getUserProfiles() method return?  In order for Struts to work, this must be an array, a Collection, an Iterator, or a Map.  The fact that your code has to call findAll() to get an iterator implies that your method does not return one of these.
[Katarina Nelson] It's return an object "UserProfiles":   

 

public UserProfiles getUserProfiles() {
      return userProfiles;
   }

 

So, is it impossible to by using the findAll() (which returns ListItrerator) iterate the "profile"?

Thanks
