Changing request Attribute via Javascript

Hi there. I have an Attribute in the request, wich was set in may action like this:
request.setAttribute("imovelDefinido", "N");

Now I want to change it in my JSP when I click on a radio button, wich means the onclick event. I think the best (or the only) way is using javascript. How can I do it?

Thanks!

You are incorrect. There is no way to do it.

While the page is sitting in the user's browser for him or her to interact with it, there is no request active. No request means no request attributes. So what are you going to change?

The request that created the HTML page to send to the broswer is long since over. And until the user submits the page (or your Javascript initiates an Ajax request), no new request will exist.

Your question indicates a fundamental misunderstanding regarding how JSP works and operates. Perhaps this article might be helpful.
