public class GetSession extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
HttpSession session = req.getSession(true);
res.setContentType("text/html");
PrintWriter out = res.getWriter();
String title = "Searching the Web";
String heading;
Integer count = new Integer(0);;
if(session.isNew()) {
heading = "Welcome, To GetID";
}
else {
heading = "Welcome Back";
Integer oldcount = (Integer)session.getValue("count");
if (oldcount != null) {
count = new Integer(oldcount.intValue() + 1);
}
}
session.putValue("count", count);
out.println(ServletValue.headWithTitle(title) +
"<body BGCOLOR=\"pink\">\n" +
"<h1 ALIGN=\"CENTER\">" + heading + "</h1>\n" +
