大家帮我看看这个web.xml文件有什么问题,在eclipse中老显示个小红叉!!

Question

web.xml的内容如下:<?xml version="1.0" encoding="GBK"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
  <servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
    <init-param>
      <param-name>config</param-name>
      <param-value>/WEB-INF/struts-config.xml</param-value>
    </init-param>
    <init-param>
      <param-name>debug</param-name>
      <param-value>3</param-value>
    </init-param>
    <init-param>
      <param-name>detail</param-name>
      <param-value>3</param-value>
    </init-param>
    <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
  
  <taglib>
  <taglib-uri>/tags/struts-html</taglib-uri>
  <taglib-location>/WEB-INF/struts-html.tld</taglib-location>
  </taglib>
  
  <taglib>
　　<taglib-uri>/tags/struts-bean</taglib-uri>
　　<taglib-location>/WEB-INF/struts-bean.tld</taglib-location>
　　</taglib>
　　
　　<taglib>
　　<taglib-uri>/tags/struts-logic</taglib-uri>
　　<taglib-location>/WEB-INF/struts-logic.tld</taglib-location>
　　</taglib>
  
</web-app>

Answer 1

红叉没猜错的话应该出现在这里：
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">这个是对xml文件结构的验证。

Answer 2

有两个叉叉
一个就是楼上那位兄弟说的那里,eclipse给出的错误原因是: cvc-complex-type.2.3: Element 'web-app' cannot have character [children], because the type's content type is element-only. 还一个是在第一个<taglib>标签那里,错误原因是: cvc-complex-type.2.4.a: Invalid content was found starting with element 'taglib'. One of '{"http://java.sun.com/xml/ns/j2ee":description, "http://java.sun.com/xml/ns/j2ee":display-name, "http://java.sun.com/xml/ns/j2ee":icon, "http://java.sun.com/xml/ns/j2ee":distributable, "http://java.sun.com/xml/ns/j2ee":context-param, "http://java.sun.com/xml/ns/j2ee":filter, "http://java.sun.com/xml/ns/j2ee":filter-mapping, "http://java.sun.com/xml/ns/j2ee":listener, "http://java.sun.com/xml/ns/j2ee":servlet, "http://java.sun.com/xml/ns/j2ee":servlet-mapping, "http://java.sun.com/xml/ns/j2ee":session-config, "http://java.sun.com/xml/ns/j2ee":mime-mapping, "http://java.sun.com/xml/ns/j2ee":welcome-file-list, "http://java.sun.com/xml/ns/j2ee":error-page, "http://java.sun.com/xml/ns/j2ee":jsp-config, "http://java.sun.com/xml/ns/j2ee":security-constraint, "http://java.sun.com/xml/ns/j2ee":login-config, "http://java.sun.com/xml/ns/j2ee":security-role, "http://java.sun.com/xml/ns/j2ee":env-entry, "http://java.sun.com/xml/ns/j2ee":ejb-ref, "http://java.sun.com/xml/ns/j2ee":ejb-local-ref, "http://java.sun.com/xml/ns/j2ee":service-ref, "http://java.sun.com/xml/ns/j2ee":resource-ref, "http://java.sun.com/xml/ns/j2ee":resource-env-ref, "http://java.sun.com/xml/ns/j2ee":message-destination-ref, "http://java.sun.com/xml/ns/j2ee":message-destination, "http://java.sun.com/xml/ns/j2ee":locale-encoding-mapping-list}' is expected.

Answer 3

建议把J2EE版本改为1.3估计两个错误都是这个原因。

Answer 4

2.4的这样定义的<jsp-config>
<taglib>
<taglib-uri>/tags/struts-html</taglib-uri>
<taglib-location>/WEB-INF/struts-html.tld</taglib-location>
</taglib><taglib>
　　<taglib-uri>/tags/struts-bean</taglib-uri>
　　<taglib-location>/WEB-INF/struts-bean.tld</taglib-location>
　　</taglib>
　　
　　<taglib>
　　<taglib-uri>/tags/struts-logic</taglib-uri>
　　<taglib-location>/WEB-INF/struts-logic.tld</taglib-location>
　　</taglib>
</jsp-config>

Answer 5

把所有跟jsp设置有关的内容都放在<jsp-config></jsp-config>里面
