如何使用tomcat 10正确配置身份验证？

我正在使用Tomcat10和eclipse开发一个j2e（或JakartaEE）web应用程序。我遵循了这个教程(http://objis.com/tutoriel-securite-declarative-jee-avec-jaas/#partie2)这看起来很旧（这是一个法语文档，因为我是法国人，如果我的英语不完美，很抱歉），但我也阅读了Tomcat10文档。
数据源工作正常，我遵循了本页上的说明(https://tomcat.apache.org/tomcat-10.0-doc/jndi-datasource-examples-howto.html#oracle_8i，并对其进行了测试，但该领域似乎不起作用，因为我无法成功登录。我总是有身份验证错误，即使我使用了正确的登录名和密码。
我尝试了很多“解决方案”来纠正这一点，但没有人奏效。我仍然不知道是否必须将领域标记放在context.xml、server.xml或两者中。我尝试了context.xml和两者，但没有发现任何区别。

这是我的项目树木，如果它可以帮助：树木
那么，有人能告诉我我做错了什么吗？
编辑：我验证了如果我们使用credentialhandler标记中指定的参数，我们是否找到了正确的哈希，它是否匹配。
这是我用来验证的java代码：

import java.security.spec.InvalidKeySpecException;

            hexChars[j * 2] = HEX_ARRAY[v >>> 4];
            hexChars[j * 2 + 1] = HEX_ARRAY[v & 0x0F];
        }
        return new String(hexChars);
    }

    {
        String password = "password";
        byte[] salt = hexStringToByteArray("e0cfcb0169f81fc46c861ecefeb7446b");

        KeySpec spec = new PBEKeySpec(password.toCharArray(), salt, 100000, 256);
        SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA512");

        byte[] hash = factory.generateSecret(spec).getEncoded();

        String res = bytesToHex(hash);
        System.out.println(res);
    }
}

我获得了与数据库中相同的编码属性（“33D6898C30FBE3E48B9A2D5A0DAD01FD8FD809C9E6A6F3911BB23A481BF0F”）
我获得了关于领域的日志：
