The getServletContext() method is introduced in Servlet 3.0, not 2.3. But if you want to get the ServletContext then an alternative method to get it is:
1 ServletContext context = request.getSession().getServletContext(); 2 3 if (username != "" & username != null ) { 4 context.setAttribute("savedUserName", username); 5 } 6 writer.println("Context Parameter : " + (String)context.getAttribute("savedUserName"));
This way you can get the stored Request Parameter Value in different browser....
