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:
<input type='hidden' name='myhiddenvalue' value='<%= request.getParameter('value') %>' />. This will then be available in the servlet as a request parameter.request.getSession()– in a JSP this is available as simplysession)I recommend using the Session as it’s easier to manage.
