Pomoč glede QueryString v JSP
noucamp90 ::
Rad bi naredil enostavno prijavno formo, ki te v primeru da ne vneseš vseh podatkov redirecta nazaj oz. na drugo formo, katera te preusmeri nazaj na prijavo. Vendar rad bi, da se prej vnešeni podatki ohranijo...v pijavi.
Hvala

Zelo preprosta forma (v datoteki na primer login.jsp):
<%@ page language="java" contentType="text/html; UTF-8" pageEncoding="UTF-8"%>
<%
if(request.getMethod().equals("POST") && request.getParameter("login") != null)
{
if(request.getParameter("username") != null && request.getParameter("username").length() > 0
&& request.getParameter("password") != null && request.getParameter("password").length() > 0)
response.sendRedirect("http://www.google.si/#q=success");
else
{
request.setAttribute("user", request.getParameter("username"));
request.setAttribute("pass", request.getParameter("password"));
}
}
%>
