How to user logic:iterate

[Michael Lee]

Im having a helluva time getting logic:iterate to work..
I have a Users object that contains an array list of
User objects.
you call Users.getUsers() and it returns an arrayList
I stick that in the request object in the perform() method using 
request.setAttribute("users", users.getUsers());
In the JSP the code I have is;

 <% ArrayList users = (ArrayList) request.getAttribute("users");
       if(users != null)
       {%>
    <logic:iterate name="users" id="aUser" scope="request">
    <tr>
      <td><bean:write name="aUser" property="user.userID"/></td>
      <td><bean:write name="aUser" property="user.userType"/></td>
      <td><bean:write name="aUser" property="user.fName"/></td>
      <td><bean:write name="aUser" property="user.mName"/></td>
      <td><bean:write name="aUser" property="user.lName"/></td>
      <td><bean:write name="aUser" property="user.accoundDisabled"/></td>
      <td><bean:write name="aUser" property="user.email"/></td>
    </tr>
    </logic:iterate>
        <%}%>

The error I'm getting is;

<Sep 9, 2002 4:52:00 PM EDT> <Error> <HTTP> <[WebAppServletContext(4398493,recei
ptsplus,/receiptsplus)] Root cause of ServletException
