I am a relatively new guy in Servlets and would be higly obliged if someone can help me with this querry. I have creted an HttpServletSession in the doPost() method of the Servlet ( for my Project of Online Exam ). There is a form in the Post method which invokes the doGet() method of the same Servlet .However in the doGet method, the browser session is NOT recognised!Why is it so ? Morever, The doGet( ) method, than , in turn invokes the doPost( ) of the same Servlet. At this stage, i.e , in the doPost( ) method the browser instance is recognised. What is the probelem ?
