You can't. All you can get back from an HTML form is a
string. That's just the way HTML works.

Wrong, but my fault because in haste I described it
wrong. By looking at the JavaDocs for either of the
interfaces you mentioned you would have seen that I
was wrong pretty quickly.

It depends on what you're trying to do, which would be
something you'll want to elucidate if you want more
effective help.

As far as I can tell you want to pass the ID of an
object in either a URL or a form then use that ID in
an action to retrieve the object and do whatever you
need to do with it.

Did the CRUD tutorial not give you the information you
think you need? It's not clear to me where you're
having issues; form and parameter handling is pretty
well covered in both the wiki and the sample apps.
