import java.io.PrintWriter;
public class HttpSessionBindingEventExample extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out = response.getWriter();
HttpSession session = request.getSession(true);
HttpSessionBindingEvent bind = null;
bind = new HttpSessionBindingEvent(session, "sessionbinding");
if (bind != null) {
out.println("sesion binding sucessfully ");
} else {
out.println("sesion binding failed");
}
}
