Using Session Scope CDI bean does not work in a HttpSessionListener




      JBoss AS 7.1.x has a bug with using session bean scope in a HttpSessionListener.

      When i inject a session scope bean in a HttpSessionListener and i try to populate attribute in sessionCreated() method many HttpSession are created by JBoss AS. Is it normal the a web server create many Http session for the same request ?

      Normally, this behaviour should work. See : http://docs.jboss.org/cdi/api/1.1-PRD/javax/enterprise/context/SessionScoped.html

      I did a light Web Project to explain the problem with 1 JSP, 1 SessionScope bean and 1 HttpSessionListener.

      Here is the code.

      JSP page :

      <%@ page language="java" contentType="text/html; charset=UTF-8"
      <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
      <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
      <title>Insert title here</title>


      SessionScope bean :

      public class UserState implements Serializable {

      private int state;

      public int getState()

      { return state; }

      public void setState(int state)

      { this.state = state; }


      HttpSessionListener :

      public class SessionListener implements HttpSessionListener {

      @Inject private UserState userState;

      public void sessionCreated(HttpSessionEvent event)

      { System.out.println("New HTTP Session created : " + event.getSession().getId()); userState.setState(2); }

      public void sessionDestroyed(HttpSessionEvent event) {}

      After execution, you can read in the console at least 2 http session creation like this :
      New HTTP Session created : zvlF6vGLP1AaXM-rzFU02wAJ.undefined
      New HTTP Session created : TlrmmA8Eu4v32SHDT0QBBZza.undefined

      The first session seams to be the one which is used by the client. There is one more problem : The polutated attributes of the session scope bean are ignored after HttpSessionListener execution. At the end all session scope attributes are null.
