堆棧跟蹤之前的長錯誤消息（為清楚起見重新格式化）解釋了問題：

java.io.IOException: org.xml.sax.SAXParseException
publicId: 
file:/home/vladimir/Downloads/glassfish-5.0/glassfish5/glassfish/lib/schemas/web-app_4_0.xsd;
lineNumber: 8; columnNumber: 27; 
Deployment descriptor file  in archive [web_war_exploded].  
TargetNamespace.1: 
Expecting namespace
'http://java.sun.com/xml/ns/javaee'
, but the target namespace of the schema document is 
'http://xmlns.jcp.org/xml/ns/javaee'.

因此，Glassfish 架構定義 ( web-app_4_0.xsd ) 中指定的命名空間與您在部署描述符 ( WEB-INF/web.xml ) 中為您的應用程序提供的命名空間不匹配。

這是 Glassfish 的web-app_4_0.xsd的頂級內容：

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns="http://www.w3.org/2001/XMLSchema"
            targetNamespace="http://xmlns.jcp.org/xml/ns/javaee"
            xmlns:javaee="http://xmlns.jcp.org/xml/ns/javaee"
            xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            elementFormDefault="qualified"
            attributeFormDefault="unqualified"
            version="4.0">
...

</xsd:schema>

請注意，為targetNamespace和xmlns:javaee指定的值是"http://xmlns.jcp.org/xml/ns/javaee" ，因此您應該在應用程序的web.xml中指定該值，而不是"http://java.sun.com/xml/ns/javaee" 。 修理：

• 停止玻璃魚
• In your application's web.xml replace all occurrences of http://java.sun.com/xml/ns/javaee with http://xmlns.jcp.org/xml/ns/javaee .
• 清理、構建和重新部署您的應用程序。
• 重新啟動 Glassfish 服務器。

I'm guessing that your problem has arisen because you have an existing application that you are migrating to use EE 8. Oracle has a useful article on schema definitions for the different EE versions titled Java EE: XML Schemas for Java EE Deployment Descriptors , and它指出對於 EE 8：

所有新模式都在http://xmlns.jcp.org/xml/ns/javaee/命名空間中。 大多數舊模式保留在http://java.sun.com/xml/ns/javaee/命名空間中。
