Well, the way I understand it, you can't do this directly:
the javascript is executed in the client's browser, *after* your jsp page has already done it's thing.
Therefor, the JSP page needs to be executed again.
The way I'd do it is to let let the javascript address the same page with your needed value as a GET or POST parameter.
Hope this solves it.
