Isn't your page fresh enough?

Refreshing the page just gives you what was already there... are you trying to CHANGE something else on the page??? [Mmmm... dreaming of how good JSF will be for this...

You might need to have your script submit the form to accomplish what you need. What needs to be refreshed (changed) on your page?

Hi my intension was to refesh the same page..so that that list value are picked up from diff tables... according to the value selected ...from html:select
any heklp

So there is a list on your page that needs to change when an option is selected... right?
There's a couple options that I can think of and both involve Javascript:
Option 1: Have the lists stored as Javascript variables.
Option 2: Have Javascript submit the page in such a way that the action adds the list to the form and forwards back to the page again.
(Option 3: JSF, but it's a lot to learn)
