recognizing session timeout [duplicate]

Answer 1

I ended up using the HttpSessionListener and refreshing in an interval larger then setMaxInactiveInterval.

So if the used did nothing for 30 Sec in the next refresh after 40 Sec I get to sessionDestroyed().

Also important that you need to create new ServletContext to get to the ServletContext.

ServletContext servletContext=se.getSession().getServletContext();

Thank you!
