> Suppose we have a web application which uses stateful session beans, and we have a HttpSessionListener like this:
> public void sessionDestroyed(HttpSessionEvent event) {
>     event.getSession().getAttribute("sfsb").remove(); // Make sure to call SFSB's @Remove method
> }
> This behavior is what Seam does.
> The HttpSessionListener.sessionDestroyed() would be called in session invalidation, session timeout and during undeploy/shutdown for cleaning up local resources. This happens in both cases, clustered and non-clustered .
> However, in clustered environment, the sfsb.remove() method call in HttpSessionListener becomes a cluster-wide operation. So when we shutdown one node, HttpSession is still available on the other node for fail over but SFSB is missing. As a result we will get javax.ejb.NoSuchEJBException: Could not find stateful bean.
