java - 引用的文件包含错误 (http ://java. sun.com/xml/ns/javaee/web-app.xsd)

Question

我在 Eclipse 中遇到了这个错误:

Referenced file contains errors (http://java.sun.com/xml/ns/javaee/web-app.xsd). For more information, right click on the message in the Problems View and select "Show Details..."

谁能帮帮我？什么是问题？提前致谢。我的代码是:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee;http://java.sun.com/xml/ns/javaee/web-app.xsd">

    <servlet-mapping>
        <servlet-name>dispatcherServlet</servlet-name>

尝试将此 URL 用于模式定义:

http://oracle.com/webfolder/technetwork/jsc/xml/ns/javaee/web-app_3_0.xsd

正如@Renardo 上面提到的，以下 URL...

http://java.sun.com/xml/ns/javaee;http://java.sun.com/xml/ns/javaee/web-app.xsd 

...重定向到在 Eclipse 中导致错误的 HTML 页面。
