这是我的 web.xml 文件

Here is my web.xml file 

 <?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">

<web-app> -->

<web-app xmlns="http://java.sun.com/xml/ns/javaee"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
                    version="3.0">
<display-name>GXT Created Web Application</display-name>



<!-- Default page to serve -->
<welcome-file-list>
    <welcome-file>guis.html</welcome-file>
</welcome-file-list>

如您所见，我在上面的 web.xml 中尝试了不同的 dtd，但问题仍然存在.希望得到任何提示

As you can see, I tried different dtds in above web.xml, but I still have the problem. Would appreciate any hints

推荐答案

您的问题是您已将 web.xml 标记为与 servlet 2.3 兼容(或者甚至可能不符合 - 我不确定您在评论中的文档类型如何被解释)

Your problem is that you have marked your web.xml as being servlet 2.3 compliant (or perhaps not even that - I am not sure how your doctype in a comment is interpreted)

 <?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">

并且您需要它至少与 servlet 2.5 兼容，Eclipse 工具才能工作.

and you need it to be at least servlet 2.5 compliant for the Eclipse tooling to work.

<?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_2_5.xsd">

(untested - copied from http://javahowto.blogspot.dk/2009/10/sample-webxml-servlet-25.html)

您可能需要重新创建 Eclipse 项目才能使更改生效.

You may need to recreate the Eclipse project to have the changes picked up.
