HttpSession session = req.getSession(true); String dsn= getInitParameter(); session.putValue("dsn",dsn); . . when i try to access the session in my JSP page as . . String sesvalue = (String)session.getValue("dsn"); out.println(" session value "+sesvalue); . . it is displays the null value can any one help as how to solve this problem. thank in advance
getValue and putValue are deprecated !. They will return null value from Version 2.2. So as Dayanad indicates use getAttribute and setAttribute. For further clarification refer Servlet API documentation. regards holla.
