Sharing session attributes in NonBlocking Handlers and Traditional Servlets

[lsgroup]

Hello,

Does anyone know how you might go about sharing session attributes between a servlet and a non-blocking handler in the same project?

        InMemorySessionManager sessman = new InMemorySessionManager(foundsessid);

        SessionAttachmentHandler sessattach = new SessionAttachmentHandler(sessman, sessconf);

        SessionManager regsessman = sessattach.getSessionManager();

        Session session;

        session = sessman.getSession(exchange, sessconf);

        //returns null

        SessionCookieConfig sessconf = new SessionCookieConfig();

        String foundsessid = sessconf.findSessionId(exchange);

        session = regsessman.getSession(foundsessid);

        System.out.println("getsession by id ="+session );

        //returns null

        session = regsessman.createSession(exchange, sessconf);

        System.out.println("create session  ="+session );

        //returns a session - but ...

1. session attributes from servlet do not return its value and

2. session attributes across http requests do not persist in memory

Also, I noticed that if the session id on a given servlet is : ABCD1234, then in the non-blocking handler side, the session id is : ABCD1234.REMOTECLIENTID

Are the two the same session or different?  I need to be able to share the user session between the two.

Thanks in advance!

Do sessions not work for non-blocking servlets?  I've tried several ways to obtain an existing session, but they all return a null object.  When I call

createSession() is creates a non-null session object that holds the same sessionid as when findSessionId(exchange) is called.  However, I can't seem to retrieving a session using that id. 

        SessionCookieConfig sessconf = new SessionCookieConfig();

        String foundsessid = sessconf.findSessionId(exchange);

        //foundsessid has value...

        SessionCookieSource sesscookiesource = sessconf.sessionCookieSource(exchange);

        InMemorySessionManager sessman = new InMemorySessionManager(foundsessid);

        session = sessman.getSession(exchange, sessconf);

        //session returns null...

        SessionAttachmentHandler sessattach = new SessionAttachmentHandler(sessman, sessconf);

        SessionManager regsessman = sessattach.getSessionManager();

        session = regsessman.getSession(exchange, sessconf);

        //session returns null...

        session = regsessman.getSession(foundsessid);

       //session returns null...

Has anyone out there gotten session to work for non-blocking handlers in Wildfly 8?

I'm not sure I understand what you're trying to do...

Why are you creating your own SessionManager instance?

Instead your servlet should use the standard HttpServletRequest.getSession(...) method to obtain a reference to the session.

In your non-blocking handler, you can access the servlet request from the exchange.

e.g.

public void handleRequest(HttpServerExchange exchange) {
     ServletRequestContext context = exchange.getAttachment(ServletRequestContext.ATTACHMENT_KEY);
     HttpServletRequest request (HttpServletRequest) context.getServletRequest();
     HttpSession session = request.getSession();
}
