I never worked with WebLogic, but from JavaDoc here I can tell that calling getPortletSession() is already wrong idea if you want to invalidate existing session, because it’s said in JavaDocs: Returns the current portlet session or, if there is no current session, creates one and returns the new session. So, it creates a new … Read more
If you want to know whether it valid based on a request: request.isRequestedSessionIdValid() or HttpSession sess = request.getSession(false); if (sess != null) { // it’s valid } If you have stored a reference to the session and need to validate I would try { long sd = session.getCreationTime(); } catch (IllegalStateException ise) { // it’s … Read more
There is no API to retrieve session by id. What you can do, however, is implement a session listener in your web application and manually maintain a map of sessions keyed by id (session id is retrievable via session.getId()). You will then be able to retrieve any session you want (as opposed to tricking container … Read more
Session-scoped beans (using scope=”session”) is the cleanest approach. This removes the need to interact with the session yourself. If you want to autowire a session-scoped bean in to the controller, you either need to make the controller session-scoped itself, or use a scoped-proxy to wire it into a singleton controller, as described here. Either approach … Read more
As Gats mentioned, the problem is that ASP.NET locks session so each request for the same session must run in serial. The annoying part is if I ran all 5 requests in serial (from the example), it’d take ~40ms. With ASP.NET’s locking it’s over 1000ms. It seems like ASP.NET says, “If session is in use, … Read more
You are not adding the object to the session, instead you are adding it to the request. What you need is: HttpSession session = request.getSession(); session.setAttribute(“MySessionVariable”, param); In Servlets you have 4 scopes where you can store data. Application Session Request Page Make sure you understand these. For more look here
No, the Servlet API doesn’t provide a way. You really have to get hold of them all with help of a HttpSessionListener. You can find several examples in the following answers: How to find HttpSession by jsessionid? How to find number of active sessions per IP? How to check Who’s Online? How to invalidate another … Read more
Firstly, is this method correct? Is there a way without touching the ServletAPI? You can use ExternalContext#invalidateSession() to invalidate the session without the need to grab the Servlet API. @ManagedBean @SessionScoped public class UserManager { private User current; public String logout() { FacesContext.getCurrentInstance().getExternalContext().invalidateSession(); return “/home.xhtml?faces-redirect=true”; } // … } what will happen to my current … Read more
Spring MVC will give you the HttpRequest if you just add it to your controller method signature: For instance: /** * Generate a PDF report… */ @RequestMapping(value = “/report/{objectId}”, method = RequestMethod.GET) public @ResponseBody void generateReport( @PathVariable(“objectId”) Long objectId, HttpServletRequest request, HttpServletResponse response) { // … // Here you can use the request and response … Read more
