The simplest choice is to use a separate HTML form for each row. You
can submit each form to a different address, if you want. But more
likely, you would submit all forms to one address, providing an item
ID. You would have a hidden field with item ID in each form, which
would be automatically submitted when form is submitted.

You do not need to send a whole item with request, but you need to
send at least an item ID, so you can send it back to the server when
you submit a form.

Here is live example:
  http://www.superinterface.com/strutsdialog/crudactionlite.do

If you look at the source code, you will see that each row is a form
with a hidden "itemId" field:
   <input type="hidden" name="itemId" value="73184">

Also, check out DisplayTag decorators:
