Yes ... your way binds you to the servlet API and will not work if you ever port the app to be a portlet. Try this instead:

UserBean user = (UserBean) map.get("user");
There are corresponding maps for request scope attributes and application scope attributes, plus a bunch of other useful information, available through the ExternalContext. Note also that the attribute maps are writeable as well as readable ... doing a map.put() operation on the map returned above will add the corresponding object as a session scope attribute in the underlying servlet or portlet session.
Hey guys,
I would like to access a session scoped backingbean ("user") from an actionListener... I'm currently doing something along the lines of:
FacesContext context = FacesContext.getCurrentInstance();
HttpServletRequest request = (HttpServletRequest)context.getExternalContext().getRequest();
HttpSession session = request.getSession();
UserBean user = (UserBean)session.getAttribute("user");
Is there a better way?
