public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException,IOException{
String userId = req.getParameter("userId");
String password = req.getParameter("password");
String uName =userId;
// if uName is null .. user is not authorized.
if (uName == null)
{
PrintWriter ot = res.getWriter();
ot.println(" Please verify the Userid and password");
ot.close();
}
else
{
// So the user is valid let's create a seesion // for this user.
HttpSession userSession = req.getSession(true);
// put the user name session variable.
userSession.putValue("userName", uName);
// now we need to transfer the control to welcome.jsp
RequestDispatcher rd =
getServletContext().getRequestDispatcher("/welcome.jsp");
