This is a very common issue. HTTP is stateless so it is the job of the programmer
to maintain state. This is what the HttpSession object is for. For each field that
you want to maintain state for, you can set it in the session. By itself, or even
better in a collection or object of some kind. The above link points to a nice
(very simple) article that outlines a framework for form processing.
enjoy.
