Action method parameters, how many, and what are they?

[Hamidam]

How can I know what parameters an action can take and return?

As of now, I know of

someAction(HttpServletResponse response, HttpServletRequest request, Model model)...

is there any more? Is there a reference for this?

What is the intention of Model, since I know you can return a ModelAndView as well...

Can you return a Model as well?

Thanks!

I suggest google which would have quite easily pointed you to the reference guide.
