Tomcat JDBC Realm登录始终失败

标签： jsf tomcat jdbc

我有一个登录示例，它是一个页面，您可以转到管理员或操作员登录...

即使使用正确的凭据，这两者都会导致servlet异常：登录失败...

在这里，希望你能帮助我：

我正在使用Tomcat内置函数来完成它而我正在使用一个简单的jsp 将表单中的结果发布到“j_security_check”。因此，用于用户名的字段名是'j_username'，密码是'j_password'（我使用的是Tomcat 8）。

    <form action="j_security_check" method="POST">
    <table>
      <tr>
        <td><label for="username">Login:</label></td>
        <td><input id="username" type="text" name="j_username" value=""></td>
     </tr>
     <tr>
     <td><label for="password">Senha:</label></td>
     <td><input id="password" type="password" name="j_password"></td> 
     <td><input type="submit" value="Login"/></td>
     </tr>
    </table>
</form>
