Why not? That is exactly what the session is for.
Request attributes disappear as soon as the request is completed. In your case,
that happens when the JSP page output is returned to the browser. The next input
(the one that goes to your servlet) is a separate request.

Save the data in the user's session. When the servlet receives the following
request, grab the data out of the session and then call session.removeAttribute()
to remove it -- that way you won't accumulate any objects that are not needed any
longer.
