When you have to access your Managed Bean in a servlet, it depends on the scope you set for the Bean.
Request-Scope:
HttpServletRequest httpRequest =(HttpServletRequest) request;YourBean bean =(YourBean) request.getAttribute("yourBean");
Session-Scope:
HttpServletRequest httpRequest =(HttpServletRequest) request;HttpSession httpSession = httpRequest.getSession();YourBean bean =(YourBean) httpSession.getAttribute("yourBean");
Application-Scope:
HttpServletRequest httpRequest =(HttpServletRequest) request;HttpSession httpSession = httpRequest.getSession();ServletContext ctx = httpSession.getServletContext();YourBean bean =(YourBean) ctx.getAttribute("yourBean");
