java - preserve search criteria in jsp page -

-

i have jsp page display list servlet, has textbox used filter search result. selecting item in list (table) , redirecting page editing details after finishing editing. able come search page via servlet, unable preserve search condition in textbox , result. how that? thinking of setting session value , in search page, correct? or there other way?

storing in session scope easiest way but, depending on how big application expected be, arise scalability issues.

as alternative, when select item in list, forward (instead of redirect because if make redirect, lose request parameters) page, passing search query parameter in request. 1 possibility have form 2 hidden fields (the query , selected item):

<form action="go_to_the_detail"> <input type="hidden" name="selecteditem" value="value_selected_item" /> <input type="hidden" name="query" value="query" /> </form>

in editing page:

<form action="go_to_save_item"> <input type="hidden" name="query" value="query_obtained_from_the_request" />  item fields modified </form>

so, when user finishes editing item, query passed again in order displayed in search box.
