(Newbie) html:link passing an object via the request object

[Davidson, Glenn]

I need to assign an object to the request object via an html:link

I am iterating over a collection of objects as such:

<logic:iterate id="doc" name="listofdocs" scope="session"
type="app.TiaaDocument">

I would like to assign the object represented by "doc" into the request
object as part of the html:link (shown below as it currently exists.

<html:link forward="editxml"
        paramId="tiaaDocument"
        paramName="doc"
        scope="session">
        Edit
</html:link>

Can anyone give me some guidance?

Thanks

Glenn
