Not having seen any code yet, its hard to judge, but I would guess you are using the JSTL <c:url> tag with <c:param> to build these links?
Using that approach it is impossible to avoid the parameters in the query string.

Do you mean that you don't know how to create an HTML form with hidden parameters? Or have you not yet realized that you need a form using the POST method if you want to connect to a URL without using URL parameters?
