<%
    //set the session the each parameter
    String locationString = request.getParameter("location");

    Integer locationId = Integer.valueOf(locationString);

You use session.setAttribute("locationId", locationString); to put attribute to session but you try to get attribute from request viarequest.getAttribute("locationId")

request.getAttribute is different from session.getAttribute
