to Regornil: when the textbox in a form, you can get its value by request.
Now I have a question:
in a JSP page, I have 2 information groups, displayed in 2 tabs. switching between that tabs by submit action. First, I input "h#7871;lô" into textbox in tab 1 then Submit. before submit, I save its value to a hidden item. then, after submit, I get value of hidden item, it don't match with before.
my JSP include:
<%@page contentType ="text/html;charset=UTF-8" %>
Give me your idea, many thanks in advance!
