I think that <jsp:useBean> action with a scope equals to "session" will put the object in the pageContext associated with the jsp page using a session scope. Therefore, this object is unavailable in the session object that you get with req.getSession() under a servlet.
Let's say you have defined an HttpSessionAttributeListener for the context, setting/unsetting session attributes in this context using jsp:setProperty will not fire any events either.
Rather ackward ain't it ?
Any comments ?
