Is it possible to use request.setAttribute
on a JSP page and then on HTML Submit get the same request attribute in the Servlet
?

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