Weld injected HttpSession into the session scoped bean is null

Question

I'm running GWT app on Jetty 6.1 with Weld 2.0. Got the next code:

    @SessionScoped
    public class SessionContext implements Serializable {

        @Inject
        private HttpSession httpSession;

        public SessionContext() {
            super();
            //at this point httpSession is null
        }
    }

What am I missing, why HttpSession is not injected? Reference says that Injecting the HttpSession will force the session to be created.

Answer 1

Change the definition of

public SessionContext() {
        super();
        //at this point httpSession is null
}

to

public SessionContext(HttpSession httpSession) {
        super();
        this.httpSession = httpSession;
        //check session here
}

Also use constructor injection

Otherwise provide a setter method for httpSession
