      public HttpSessionAccess()

  • Method Details

    • initialize

      public static void initialize(javax.servlet.ServletContext servletContext)

    • getCurrentFacesContext

      public static javax.faces.context.FacesContext getCurrentFacesContext()
      Accessing the FacesContext. You should use this method instead of directly accessing FacesContext.getCurrentInstance() in case you pass the FacesContext into non-UI threads.

    • getCurrentFacesApplication

      public static javax.faces.application.Application getCurrentFacesApplication(javax.faces.context.FacesContext context)
      Accessing the Application. This method is already considering cases in which the application is accessed from a non-UI thread.

    • getCurrentELContext

      public static javax.el.ELContext getCurrentELContext(javax.faces.context.FacesContext context)
      Accessing the EL context which is for accessing expressions. This method is already considering cases in which the application is accessed from a non-UI thread.

    • getCurrentHttpSession

      public static javax.servlet.http.HttpSession getCurrentHttpSession()
      This session must only be called within the context of a request processing!

      Please pay attention: call function getCurrentDialogSession() if you want to access the session that is managed per browser tab instance! The http session may sapn several browser tabs - if using COOKIEs for session management!

    • getCurrentHttpSessionIfAvailable

      public static javax.servlet.http.HttpSession getCurrentHttpSessionIfAvailable(javax.faces.context.FacesContext context)
      Same as getCurrentHttpSession() - now with passing the FacesContext instance, which guides to the http session and now without creating the http session if it does not exist.

      Please pay attention: call function getCurrentDialogSession() if you want to access the session that is managed per browser tab instance! The http session may sapn several browser tabs - if using COOKIEs for session management!

    • getCurrentHttpSessionIfAvailable

      public static javax.servlet.http.HttpSession getCurrentHttpSessionIfAvailable(ISessionContextProvider context)

    • getCurrentHttpSession

      public static javax.servlet.http.HttpSession getCurrentHttpSession(javax.faces.context.FacesContext context)
      Same as getCurrentHttpSession() - now with passing the FacesContext instance, which guides to the http session.

      Please pay attention: call function getCurrentDialogSession() if you want to access the session that is managed per browser tab instance! The http session may sapn several browser tabs - if using COOKIEs for session management!

      Counter part of addGlobalHttpSessionListener(IHttpSessionListener).

    • addHttpSessionCloseReactorForCurrentSession

      public static void addHttpSessionCloseReactorForCurrentSession(String id, IHttpSessionClosedReactor reactor)
      Adds a reactor interface into the current http session which notifies about closing the session. Pleas pay attention to the difference between http-session and dialog-session (URL- or COOKIE-based session management). If you want to get notified about the "per-browser-session" then use addDialogSessionClosedReactorForCurrentSession(ISessionAbstractionListener).

    • removeHttpSessionCloseReactorForCurrentSession

      public static void removeHttpSessionCloseReactorForCurrentSession(String id)

      The context path is a string like "/demos" - and is the URL prefix that is uniquely used for the web application within the servlet container. The name of the application is taken from the context path - without leading slash. In case the context path is the root context path ("/") then "root" is returned.

      During (JUnit) testing, the servlet context might not be available. Use UsageWithoutSessionContext to indicate that you are running in test mode - in this case "undefined" is returned.

    • getServletTempDirectory

      public static String getServletTempDirectory()
      A servlet context provides access to a temporary directory in which you can write or read data. Pay attention: in a clustered scenario the temp directory might be different from request to request - because the session might be migrated from one server to the next.

      Returns the servlet request that triggered the current request processing. This functions is expected to be called as part of the default request/response processing.

      If called outside this processing, then null will be returned.

    • getCurrentLocationHref

      Returns the servlet response of the current request processing. This functions is expected to be called as part of the default request/response processing.

      public static boolean checkIfInLayoutEditorPreview()
      Passes back information if the current dialog is opened in the preview mode of the editor. This method returns true only for the first request that is sent from the preview to the server side processing. Subsequent requests are always treated as "normal" requests. Please check the method checkIfDialogSessionInLayoutEditorPreview().
      Returns:
      "true" if opened in layout editor preview - for the first request
      "false" otherwise

    • checkIfDialogSessionInLayoutEditorPreview

      public static boolean checkIfDialogSessionInLayoutEditorPreview()

    • getCurrentClientId

      public static String getCurrentClientId()
      Passes back an id that is associated with the client. The client id is some explicit id that identifies the client on a long term (or at least: longer than the life cycle of a session).

      In the RISC client the client id is stored as cookie. The client id is automaitcally generated if it does not exist yet. - You can epplicitly set the client id by using ServletUtil.writeEclntIdCookie(HttpServletResponse, String). Or you may set by using the html page: eclntjsfserver/utilpages/setclientid.html within your web application.

    • getCurrentClientId

      public static String getCurrentClientId(boolean createClientIdIfNotExists)

    • setCurrentClientId

      Explicitly set the client id to some defined value.

    • getCurrentLocale

      public static Locale getCurrentLocale()
      Retrieve the Locale that is used on server side within the current session. In normal situations this is taken from the viewRoot of the FacesContext - but sometimes this function is also used outside a valid FacesContext (e.g. when downloading information). In this case the Locale is taken from the session context.

      In case there is no session available then the Locale of the server environment is returned.

      Pay attention: the localization of the client may be different! You get this localization by calling getCurrentClientLocale().

    • setCurrentLocale

      public static void setCurrentLocale(Locale l)
      Sets the locale that is passed as locale for the current session.

    • setCurrentStyle

      public static void setCurrentStyle(String style)

      public static String getCurrentStyle()
      Returns the current style for the session.

    • reloadClient

      public static void reloadClient()
      Sends a signal to the client side that triggers a reload of the complete page - within the current session (i.e. no new session is created). This method is e.g. used when updating the style of the client - in this case all the server side components need to be re-created, which is exactly done through the reload.

    • reloadClient

      public static void reloadClient(javax.servlet.http.HttpServletResponse response)

    • getCurrentSubpageContext

      public static SubpageContext getCurrentSubpageContext()

      public static SubpageContext getCurrentSubpageContext(javax.servlet.http.HttpSession session)
      Access to the subpage context, which is available if one Http-session is shared across multiple browser instances - due to using cookies for session tracking.

    • getCurrentDialogSession

      public static ISessionAbstraction getCurrentDialogSession()
      The dialog session is the session that is associated with a dialog ("browser tab instance") on client side. In case of using URL-encoding for session management this is a wrapper around the http-session. In Cas of using COOKIEs for session management this is a wrapper around the subpage context.
