我正在尝试使用PostgreSQL数据库在Java应用程序中实现基于表单的身份验证。当我在登录页面上登录时，server.log中出现异常。有很多行，但是对我来说最突出的是一行relation "users" does not exist。在数据库的默认“公共”模式下，我肯定有一个“用户”表。无论如何，这是此错误的完整堆栈跟踪：

以下是security-domain中security-domains部分下的相关standalone.xml：
<security-domain name="FBADomain">
<authentication>
<login-module code="Database" flag="required">
<module-option name="dsJndiName" value="java:/PostgresDS"/>
<module-option name="principalsQuery" value="SELECT password FROM users WHERE username = ?"/>
<module-option name="rolesQuery" value="SELECT role, 'Roles' FROM user_roles WHERE username = ?"/>
</login-module>
</authentication>
</security-domain>
