No. Regardless of whether you use a session anywhere, the container manages it.
Never create a session on your own. Never. Ever.

Don't ever use new to get a session.
In your JSP use the "session" variable created for youby the container.
In the servlet, use request.getSession().
Always let the container handle the creation of the session.
