What is standard web.xml java header to get <jsp-config> tag working?
提问by user46688
I've got a GlassFish 3.1.2 app server and I've started using JSP pages so I'm interested in configuring the encoding correctly for UTF-8.
我有一个 GlassFish 3.1.2 应用服务器，并且我已经开始使用 JSP 页面，所以我对正确配置 UTF-8 编码很感兴趣。
My original working web.xmlfile started with
我的原始工作web.xml文件以
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
but then I added the following to it to force UTF-8 encoding
但后来我添加了以下内容以强制使用 UTF-8 编码
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<page-encoding>UTF-8</page-encoding>
</jsp-property-group>
</jsp-config>
and my GlassFish 3.1.2 server log file reported
和我的 GlassFish 3.1.2 服务器日志文件报告
Element type <jsp-config> must be declared web.xml
In an attempt to fix the error, I changed the start of my web.xmlfile to be
为了修复错误，我将web.xml文件的开头更改为
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4" >
and now I'm getting a GlassFish server error
现在我收到 GlassFish 服务器错误
Invalid Deployment Descriptors in Deployment descriptor file WEB-INF/web.xml ...
One of '{"http://java.sun.com/xml/ns/j2ee":servlet-class,
"http://java.sun.com/xml/ns/j2ee":jsp-file}' is expected.
Is my syntax off? How to get <jsp-config>working with header in xml.webfile for version 2.3?
我的语法关闭了吗？如何<jsp-config>使用xml.web2.3 版文件中的头文件？

Alternatively, I also have a glassfish-web.xmlfile in WEB-INFdirectory. If I revert the web.xmlfile back to original and place the <jsp-config>section in glassfish-web.xmlinstead of web.xml, the server starts fine. Which file is <jsp-config>supposed to go in, or does it matter?
或者，我glassfish-web.xml在WEB-INF目录中也有一个文件。如果我将web.xml文件恢复为原始文件并将该<jsp-config>部分放在glassfish-web.xml而不是 中web.xml，则服务器启动正常。<jsp-config>应该放入哪个文件，或者这重要吗？

To configure JSP with UTF-8 you need to use, at the first line of the jsp:
要使用 UTF-8 配置 JSP，您需要使用，在 jsp 的第一行：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
You should use this but with your version:
您应该使用它，但与您的版本一起使用：
<?xml version="1.0" encoding="UTF-8"?>
