What I still don't understand is why are you using two nested iterate
tags? You only need one tag to iterate over the contents of a Vector.
If you have a session attribute named "buddylist" that is a Vector,
iterate over it like this:
<table>
<logic:iterate id="buddy" name="buddylist" scope="session">
<tr>
<td><bean:write name="buddy" property="name" filter="true"/></td>
</tr>
</logic:iterate>
</table>
Note that you refer to buddylist with a *name* attribute, not a *property*
attribute.
