iterate problem

[Moons Manuel]

Hello everyone.

I am currently having some problems with iterating over an array of objects.

In my action class I have put an array into the session object
(request.getSession().setAttribute("orderedsandwiches",...);)

I would like to loop over these objects in my jsp page.

I am trying to do this like this:

<bean:define id="orderedsandwiches" name="orderedsandwiches"/>

<table>
<logic:iterate id="element" name="orderedsandwiches">
        <tr>
        <td>
        <bean:write name="element" property="name"/>
        </td>
        </tr>
</logic:iterate>
</table>


But when I try to do this, I get an exception like the following:

<9-jul-01 14:21:07 GMT+02:00> <Error> <HTTP>
<[WebAppServletContext(5325170,sandwich)] Root cause of ServletException

When I loop through the array using jsp snippets, I can print out the
contents of the array like this:


<table>
<%
  OrderBean []ob = (OrderBean[])orderedsandwiches;
  for(int i=0;i<ob.length;i++) {
        %><tr><td><%
        out.println(ob[i]);
        %><td><tr><%
  }
%>
</table>

The strange thing about all of this is that in another jsp page, I do almost
the same thing and there this works without any problems.

Does anyone have an idea to solve this problem????
