我正在尝试使用 Eclipse 2018-09 和 Payara 5 在开发中部署一个示例 JSF 2.3 应用程序，但它返回了此错误：
2018-10-14T15:19:42.783-0300|Severe: Exception during lifecycle processing java.io.IOException: org.xml.sax.SAXParseException; lineNumber: 8; columnNumber: 15; Deployment descriptor file META-INF/persistence.xml in archive [classes]. cvc-complex-type.2.4.b: The content of element 'persistence' is not complete. One of '{"http://xmlns.jcp.org/xml/ns/persistence":persistence-unit}' is expected.
这是我persistence.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
http://xmlns.jcp.org/xml/ns/persistence/persistence_2_2.xsd"
version="2.2">
<!-- JPA configuration here. -->
</persistence>
这是我的控制台输出的摘录：

我该如何解决这个问题？
谢谢。
您需要为持久性.xml文件提供持久性单元信息
下面是一个示例：https://www.thoughts-on-java.org/jpa-persistence-xml/
希望对您有所帮助！
