hi edward,
do you mean get the value in the following page or in the same page?
remember the HTTP protocol uses a request-response action, meaning that once
a page is loaded the java variables are assigned and can't be changed
dynamically, to do such comparisons with out loading a new page use
javascript.
on the following page the request.getParameter("flag"); should work if
you've submitted the form.
if the hidden variable doesn't change after the page gets loaded up then you
can just assign a java variable to the same value that the hidden value gets
assigned.
