Re: [undertow-dev] Sharing session attributes in NonBlocking Handlers and Traditional Servlets
Basically you need to use io.undertow.servlet.spec.ServletContextImpl#getSession().
If your handler is running after the initial servlet handler you can get this from the
io.undertow.servlet.handlers.ServletRequestContext, which is attached to the exchange.
If you are running before the initial handler you need to store a reference to the servlet
context or the Deployment somewhere.
Servlet does not use SessionAttachmentHandler, because each servlet context can have its
own session with its own settings, and multiple contexts can be involved in the same
request if forward/include is used. As a result each servlet context has its own session
manager, and manages it internally.

Subject: [undertow-dev] Sharing session attributes in NonBlocking Handlers and
Traditional Servlets
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
Thanks in advance!
