网络应用程序 web.xml 错误 [英] web app web.xml error

问题描述

我在 Eclipse 中开发的 GWT 应用程序出错.它位于 web.xml 文件中.这是错误:

I am getting an error in my GWT application being developed in Eclipse. It's in the web.xml file. Here's the error:

The content of element type "web-app" must match "(icon?,display-   name?,description?,distributable?,context-
     param*,filter*,filter-mapping*,listener*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-
     file-list?,error-page*,taglib*,resource-env-ref*,resource-ref*,security-constraint*,login-config?,security-
     role*,env-entry*,ejb-ref*,ejb-local-ref*)".

我看过很多关于这个的帖子，问题是文件元素的顺序，但这个修复对我不起作用(我也试过把所有的 <servlet-mapping> 标签紧跟在相应的 之后，它也不起作用)

I have seen numerous posts about this and the problem is the order of the elements of the file, but that fix doesn't work for me (I have also tried putting all the <servlet-mapping> tags right after the corresponding <servlet>, it did not work either)

我的 web.xml 文件:

<?xml version="1.0" encoding="UTF-8"?>

</web-app>

是否有其他方法可以跟踪此错误；与此链接的其他文件?

Are there any other ways of tracking this error; other files that are linked to this?

推荐答案

我删除了文件并将旧文件中的文本粘贴到同名的新文件中，现在没有错误.

I deleted the file and pasted the text from the old one into a new file with the same name and now there's no errors.
