State Management and the HttpSession

This free, multimedia tutorial shows you how to use IBM's Rational Application Developer (IRAD) 6.0 to create a simple Servlet that takes advantage of the HttpSession object of the Servlet and JSP API. The simple Servlet uses a hitcounter to keep track of the number of times the petulant user refreshes the web page.

public class SessionServlet extends HttpServlet implements Servlet {

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
HttpSession session = request.getSession(false);
if (session == null){
session = request.getSession(true);
Integer hitCount = new Integer(0);
session.setAttribute("count", hitCount);
}
Integer hitCount = (Integer)session.getAttribute("count");
hitCount = new Integer(hitCount.intValue() + 1);
session.setAttribute("count", hitCount);
response.getWriter().print("Number of times at this page: " + hitCount.intValue());
}
}
