Adding a object to the next request

Question

Hi all,
Suppose your in a JSP section at the top of your page, and later there is an html button, that will submit the form. I know you can write code such as:
    request.setAttribute("name", object);However, that attribute is set to the previous request. (Which seems mostly useless.) However, suppose I wanted the object to be added to the next request. The request when the user click the button.
I know about hidden inputs, but I want to add actually objects to the request, not just strings. Besides, it is kind of a pain, to add a different hidden input every time you want to add an object to the next request.
I like how session works, with session.getAttribute(name) and session.setAttribute(name, value).
What advice do you guys have?

It turns out hiddenInput is only for strings, not objects. I am not using tomahawk or a4j, so I can't use either of them. Do you have any other ideas?
I was thinking of using a session scope Map, and adding the object to the map, and passing the key to the next page as hidden input. However, I am having a little trouble telling when and how to add it to the map.
I want the object to accept input from the gui, and then be saved. Basically, I think I need to grab the object at a phase after the data is added to the object, but before the object it deleted. I don't know a lot of the phase listeners, so I am not sure how to do what I want to do.
Do you have any ideas how I would do that, or a better way to do the same thing?
