Here, I am pasting an answer from already asked question Using request.setAttribute in a JSP page

No. Unfortunately the Request object is only available until the page finishes loading - once it's complete, you'll lose all values in it unless they've been stored somewhere.

If you want to persist attributes through requests you need to either:

1.Have a hidden input in your form, such as " />. This will then be available in the servlet as a request parameter.

2.Put it in the session (see request.getSession() - in a JSP this is available as simply session)

I recommend using the Session as it's easier to manage.
