Hello Hippo,
I am new to hippo and working on hippo cms site.
I am working on creating a login page with spring security. For this I created the following files and did the configuration for spring and spring security.
Here is my Login.jsp.<%@ taglib prefix="c" uri="
http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
<title>Login Page</title>
<style>
.errorblock {
color: #ff0000;
background-color: #ffEEEE;
border: 3px solid #ff0000;
padding: 8px;
margin: 16px;
}
</style>
</head>
<body onload='document.f.j_username.focus();'>
<h3>Login with Username and Password (Custom Page)</h3>
<c:if test="${not empty error}">
<div class="errorblock">
Your login attempt was not successful, try again.<br /> Caused :
${sessionScope["SPRING_SECURITY_LAST_EXCEPTION"].message}
</div>
</c:if>
<form name='f' action="/j_spring_security_check"
method='POST'>
<table>
<tr>
<td>User:</td>
<td><input type='text' name='j_username' value=''>
</td>
</tr>
<tr>
<td>Password:</td>
<td><input type='password' name='j_password' />
</td>
</tr>
<tr>
<td colspan='2'><input name="submit" type="submit"
value="submit" />
</td>
</tr>
<tr>
<td colspan='2'><input name="reset" type="reset" />
</td>
</tr>
</table>
</form>
</body>
</html>

This module also contains registration part using spring thar part is working fine . On the login page I fill the
correct username and password and clicks "Login" button. The url goes to
"http://localhost:8080/site/j_spring_security_check"and redirects to
PAGE NOT FOUND instead of success and fail.No authentication process initatied after clicking on "Login" button.
I am not able to understand why it is not working
However the same
code and configuration is working fine in eclipse as a spring application.Please help me to get this working.Regards,
Pranav
