当我在Eclipse Helios Service Release 2中构建我的项目时,我的错误web.xml.请建议我为此做些什么.在我的项目中,我使用的是DTD 2.2.错误如下.

元素类型"web-app"的内容必须匹配"(icon？,display-name ?, description？,distributable？,context-param*,servlet*,servlet-mapping*,session-config？,mime- mapping*,welcome-file-list？,error-page*,taglib*,resource-ref*,security-constraint*,login-config？,security-role*,env-entry*,ejb-ref*)".

我的web.xml文件有问题.错误:

元素类型"web-app"的内容必须匹配"(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进入*,EJB-REF*,EJB本地-REF*)".

但是,我的web.xml文件按错误说的顺序排列.

这是我的web.xml:

<!DOCTYPE web-app PUBLIC
         "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
         "http://java.sun.com/dtd/web-app_2_3.dtd" >

    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>/faces/*</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>

</web-app>

我使用WebLogic 10.3.4.对这个问题有什么看法吗？
