You … Read more

All you need to do is to just not to get a handle of it by either request.getSession() or request.getSession(true) anywhere in your webapplication’s code and making sure that your JSPs don’t implicitly do that by setting <%@page session=”false”%>.

You need to put the JSP file in /index.jsp instead of in /WEB-INF/jsp/index.jsp. This way the whole servlet is superflous by the way.
