		ValueStack request = ActionContext.getContext().getValueStack();
		
		HttpServletRequest request = ServletActionContext.getRequest();
		
		HttpServletRequest request = (HttpServletRequest)ActionContext.getContext().get(ServletActionContext.HTTP_REQUEST);

 

session:

HttpSession session = ServletActionContext.getRequest().getSession();

HttpSession session = (HttpSession)ActionContext.getContext().get(ServletActionContext.SESSION);

Map map = (Map)ActionContext.getContext().getSession();
