i am using spring security and i am wondering how to change the default login form
i have found out that i need to point to my new form location. i want to keep the existing functions of the existing default form that has all the login exception display. so i must know how to reproduce it first.
in my research i come across with it
http://www.codercorp.com/blog/spring/security-spring/spring-security-login-logout-form.html
thanks him for the code
<%@ taglib prefix='c' uri='http://java.sun.com/jstl/core_rt' %>
<%@ page import="org.springframework.security.ui.AbstractProcessingFilter" %>
<%@ page import="org.springframework.security.ui.webapp.AuthenticationProcessingFilter" %>
<%@ page import="org.springframework.security.AuthenticationException" %>
<html>
<head>
<title>Login</title>
</head>
<body>
<h1>Login</h1>
<c:if test="${not empty param.login_error}">
<font color="red">
Your login attempt was not successful, try again.<br/><br/>
Reason: <c:out value="${SPRING_SECURITY_LAST_EXCEPTION.message}"/>.
</font>
</c:if>
<form name="f" action="<c:url value='j_spring_security_check'/>" method="POST">
<table>
<tr><td>User:</td><td><input type='text' name='j_username' value='<c:if test="${not empty param.login_error}"><c:out value="${SPRING_SECURITY_LAST_USERNAME}"/></c:if>'/></td></tr>
<tr><td>Password:</td><td><input type='password' name='j_password'></td></tr>
<tr><td><input type="checkbox" name="_spring_security_remember_me"></td><td>Don't ask for my password for two weeks</td></tr>
<tr><td colspan='2'><input name="submit" type="submit"></td></tr>
<tr><td colspan='2'><input name="reset" type="reset"></td></tr>
</table>
</form>
</body>
</html>
but the code seems not working well for spring security 3. some libraries where outdated and i replaced them one by one. i change them to this below
<%@ page import="org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter" %>
<%@ page import="org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter" %>
<%@ page import="org.springframework.security.core.AuthenticationException" %>
but it is still refuse to report login errors. what else should i try ?
