Eclipse报告问题在我的web.xml中，但它处理得很好 [英] Eclipse reporting problem in my web.xml, but it is processed fine

问题描述

我在Eclipse中使用带有Google插件的Google App Engine，这里是我的web.xml的头文件：

$ b

 <？xml version =1.0encoding =utf-8？> 
< web-app xmlns：xsi =http://www.w3.org/2001/XMLSchema-instance
 xmlns =http://java.sun.com/xml/ns / javaee
 xmlns：web =http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd
 xsi：schemaLocation =http：//java.sun .com / xml / ns / javaee 
 http://java.sun.com/xml/ns/javaee/web-app_2_5.xsdversion =2.5> 
  

基于一些GAE文档，我添加了这个：

 < security-constraint> 
< web-resource-collection> 
< url-pattern> / tasks / *< / url-pattern> 
< / web-resource-collection> 
< auth-constraint> 
<角色名称>管理员< /角色名称> 
< / auth-constraint> 
< / security-constraint> 
  

然而Eclipse在url-pattern报告错误：

cvc-complex-type.2.4.a：发现以元素'url-pattern'开头的无效内容。

其中一个'{http： //blank.sun.com/xml/ns/javaee\":web-resource-name}'是预期的。

我可以启动应用程序，它似乎处理web.xml文件就好了，但我不喜欢Eclipse报告错误的事实。问题是什么？

解决方案

嗯，这个错误看起来非常简单 - 它在url之前预期的web-resource-name标记-pattern：）

干杯

I'm using Google App Engine with the Google plugin in Eclipse, here is the header of my web.xml:

<?xml version="1.0" encoding="utf-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">

Based on some of the GAE documentation, I added this:

<security-constraint>
    <web-resource-collection>
        <url-pattern>/tasks/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
        <role-name>admin</role-name>
    </auth-constraint>
</security-constraint>

However Eclipse reports an error at "url-pattern":

cvc-complex-type.2.4.a: Invalid content was found starting with element 'url-pattern'.
One of '{"http://java.sun.com/xml/ns/javaee":web-resource-name}' is expected.

I can start the app and it seems to process the web.xml file just fine, but I don't like the fact that Eclipse is reporting an error. What is the problem?

解决方案

well, the error seems pretty straightforward - a web-resource-name tag it expected before the url-pattern :)
