堆栈跟踪之前的长错误消息(为了清晰起见，已重新格式化)解释了问题：
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的模式定义(web-app_4_0.xsd)中指定的命名空间与您在应用程序的部署描述符(web-INF/web.xml中提供的命名空间不匹配。
这是Glassfish的web-app_4_0.xsd:的顶级内容
<?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>
请注意，为targetNamespace和xmlns:javaee指定的值是"http://xmlns.jcp.org/xml/ns/javaee"，因此应该在应用程序的web.xml中指定该值，而不是"http://java.sun.com/xml/ns/javaee"。要修复：
- 停止Glassfish
- 在应用程序的web.xml中，用
http://xmlns.jcp.org/xml/ns/javaee替换所有出现的http://java.sun.com/xml/ns/javaee - 清理、构建和重新部署您的应用程序
- 重新启动Glassfish服务器
我猜您的问题之所以出现，是因为您有一个现有的应用程序正在迁移以使用EE8。Oracle有一篇关于不同EE版本的模式定义的有用文章，标题为JavaEE:JavaEE部署描述符的XML模式，它指出，对于EE8:
所有新架构都在中http://xmlns.jcp.org/xml/ns/javaee/命名空间。大多数较旧的模式保留在http://java.sun.com/xml/ns/javaee/命名空间。
