这几天在用WTP时，web.xml文件老是报错：
Referenced file contains errors (http://www.ibm.com/webservices/xsd/j2ee_web_services_client_1_1.xsd). For more information, right click on the message and select "Show Details..."，按照提示，查看"Show Details..."，错误如下：
The errors below were detected when validating the file "j2ee_web_services_client_1_1.xsd" via the file "web.xml". In most cases these errors can be detected by validating "j2ee_web_services_client_1_1.xsd" directly. However it is possible that errors will only occur when j2ee_web_services_client_1_1.xsd is validated in the context of web.xml.
web.xml配置文件是WTP自动生成的，如下：
<!-- sp --> xml version="1.0" encoding="UTF-8"?> < web-app id ="WebApp_ID" version ="2.4" xmlns ="http://java.sun.com/xml/ns/j2ee" xmlns:xsi ="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation ="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" > < display-name > Ajaxdisplay-name> < welcome-file-list > < welcome-file > index.htmlwelcome-file> < welcome-file > index.htmwelcome-file> < welcome-file > index.jspwelcome-file> < welcome-file > default.htmlwelcome-file> < welcome-file > default.htmwelcome-file> < welcome-file > default.jspwelcome-file> welcome-file-list> web-app>这个web.xml文件是不会有问题的，难道是web.xml文件的验证文件更换了？
上网下载了Lomboz，新建一个动态WEB工程，也报同样的错误，但用MyEclipse打开却没有这个问题，郁闷！！
