新建struts项目后，web.xml报错

    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"

        </filter>

            <welcome-file>index.jsp</welcome-file>
        </welcome-file-list>
    </web-app>

解决办法：将org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter改为

org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter

启动Tomcat,出现以下错误

解决办法：在WEB-INF目录下新建lib文件，将struts的jar包拷贝到lib目录下

![70][]

然后将所有jar文件选中，右击jar文件，选择Add as Library 。

重启Tomcat成功。
