Solution

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:

ServletContext context = request.getSession().getServletContext();

if (username != "" & username != null ) {
    context.setAttribute("savedUserName", username);
}
writer.println("Context Parameter : " + (String)context.getAttribute("savedUserName"));

This way you can get the stored Request Parameter Value in different browser....
