httpsession

Hey guys. I'm trying to get a session bean in a HttpSessionListener so that when the user logs out or the session expires I can delete some files that the user created in the application. I'm guessing the session bean doesn't exist because the session is destroyed. I was hoping to still delete these files some how. Thanks for the help. @WebListener public class SessionListener implements HttpSessionListener { @Override public void sessionCreated(HttpSessionEvent se) { HttpSession session = se.getSession(); System.out.print(getTime() + " (session) Created:"); System.out.println("ID=" + session

HttpSession is a high level interface built on top of cookies and url-rewriting, which means that there is only a session ID is stored in client side and the data associated with it is stored in server side. Where is the HttpSession data actually stored in the server side? In the JVM memory or somewhere else? Can I change the place where to store it, e.g. save them into an in-memory database? If it's not in a database, is there any concurrency problem when many clients work on the same session data at the same time? It's up to the server where to store session data; the ones I'm familiar with

Is it possible to configure two separate web apps (WAR) in a J2EE application (EAR) to access a shared session context? Further info: I ended up creating a shared class from the EAR which stored the required information in static members. This did the trick, even if it seemed like a dirty hack. Not directly. Most containers put each WAR in a separate classloader with the EAR classloader as their parent. Each app's sessions are separate. You can put something provided by the parent EAR in each session. If you need them to share something, make it a EAR function. As far as i've read and seen, it

I have in my application polling HTTP requests that executed each 5 minutes. I want to configure those URLs not to change the session expiration. Otherwise my session will never expired (and I do not want it). Was not able to find it in the web.xml and HttpSession documentation. How is possible to do it? Added Very important clarification: the request should be authenticated. It means that the request should be attached to JsessionID that is already authenticated. Clarification (Added 2) I do not want the session will expire regardless of whether the user stays active or not. I want the

I need to write a servlet that, when called, gets information about a list of the currently opened sessions. Is there a way to do this? Implement HttpSessionListener , give it a static Set<HttpSession> property, add the session to it during sessionCreated() method, remove the session from it during sessionDestroyed() method, register the listener as <listener> in web.xml . Now you've a class which has all open sessions in the current JBoss instance collected. Here's a basic example: public HttpSessionCollector implements HttpSessionListener { private static final Set<HttpSession> sessions =

I have a very simple Servlet and a very simple HttpSessionListener: @WebServlet("/HelloWorld") public class HelloWorld extends HttpServlet { private static final long serialVersionUID = 1L; @Override public void init(ServletConfig config) throws ServletException { super.init(config); getServletContext().setAttribute("applicationHits", new AtomicInteger(0)); } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("get"); ((AtomicInteger) request.getServletContext().getAttribute("applicationHits")).incrementAndGet
