用于基于表单的身份验证的Tomcat 7领域配置

Question

I am quite new to Java EE and was starting out with tomcat. 我对Java EE还是很陌生，并且从tomcat开始。 I am developing a small task application with PrimeFaces. 我正在使用PrimeFaces开发一个小型任务应用程序。

The application has a main page and admin area which is protected by the web.xml file. 该应用程序具有主页和管理区域，该区域由web.xml文件保护。 When i develop the login page according to guidelines posted here http://docs.oracle.com/cd/E19159-01/819-3669/bncby/index.html . 当我根据http://docs.oracle.com/cd/E19159-01/819-3669/bncby/index.html中发布的指南开发登录页面时。 I cannot login although I have configured the realm properly. 尽管我已经正确配置了领域，但是我无法登录。

I read this post on JSP web application form based authentication in tomcat which is exactly the problem I have. 我在基于Tomcat的JSP Web应用程序表单身份验证上阅读了这篇文章，这正是我遇到的问题。 But I am not using Eclipse. 但是我没有使用Eclipse。
These are my codings and XML configuration files. 这些是我的编码和XML配置文件。

The login.jsp page login.jsp页面

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Log In</title>
</head>
<body>
    <form method="post" action="j_security_check">
        <p>Username</p>
        <input type="text" name="j_username" />
        <p>Password</p>
        <input type="password" name="j_password" />
        <p></p>
        <input type="submit" value="Submit" /> <input type="reset"
            value="reset" />
    </form>
</body>
</html>

The web.xml file web.xml文件

This is how I have prepared the database tables, database is called 'todo'. 这就是我准备数据库表的方式，数据库称为“ todo”。

mysql> SELECT * FROM users;
+----------+----------+
| username | password |
+----------+----------+
| lal      | lal      |
| lala     | lala     |
| mad      | mada     |
| nalaka   | nalaka   |
+----------+----------+
4 rows in set (0.00 sec)

mysql> SELECT * FROM user_roles;
+----------+------------+
| username | rolename   |
+----------+------------+
| lal      | sales      |
| lala     | management |
| lala     | sales      |
| mad      | admin      |
| nalaka   | sales      |
+----------+------------+
5 rows in set (0.00 sec)

I have to use user mad to login because in the web.xml file I have specified the role as admin to login to the admin area. 我必须使用用户疯狂登录，因为在web.xml文件中我指定的角色为管理员登录到管理区。 When I use the username and password as mad and mada respectively, I get redirected to the error page. 当我分别使用用户名和密码mad和mada时，我将重定向到错误页面。 And the URL is appended with j_security_check like this. URL像这样附加j_security_check。

http://localhost:8081/ToDoApplication/admin/j_security_check

The database user tomcat has SELECT privileges for the todo database. 数据库用户tomcat对todo数据库具有SELECT特权。 The tomcat guide mentioned that since the tomcat server wont be writing to the database, the user must at least have read privileges. tomcat指南提到，由于tomcat服务器不会写入数据库，因此用户至少必须具有读取特权。

错误发生在server.xml的“ userRolesTable”中，应为“ userRoleTable”
