Hy!
I have a jsp site called konto (engl. account) At the end i have a button that should invalidate the current session by clicking and redirect back to the loginpage but that doesn't work.
Code:
<%@page contentType="text/html" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <jsp:useBean id="konto" scope="session" class="at.korn.web.Konto"></jsp:useBean> <% if (session.getAttribute("user")== null) { %> <jsp:forward page="index.jsp"></jsp:forward> <% } if (request.getParameter("logout")!= null) { session.invalidate(); %> <jsp:forward page="index.jsp"></jsp:forward> <% } %> <% konto.holeKontostand(String.valueOf( session.getAttribute("user")));%> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Konto</title> </head> <body> <h1>Kontoübersicht</h1> <p>Herzlich Willkommen <% out.print(session.getAttribute("user"));%> </p> <p>Ihr Kontostand beträgt: ${konto.ktostand} </p> <input type="submit" value="Logout" name="logout" /> <br> </body> </html> The Error should be in that file. Please help!
