我编写了下面提到的struts.xml文件并在Eclipse上运行，但是我得到了一个错误。
我也直接清洁雄猫工作
错误是：

我的struts.xml文件是：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

答案已经在堆栈跟踪:)
原因：org.xml.sax.SAXParseException; systemId： file：/D：/Sonali_workplace/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/salesdeals123/WEB-INF/classes/struts.xml; 行号： 22;列数： 21;元素类型"操作映射"必须 被声明。
错误罪魁祸首的文件在WEB-INF/classes/struts.xml中。
struts.xml配置文件应位于源文件夹中， 如src或resources。构建应用程序时 编译输出定向到WEB-INF/classes。你可以检查这个文件 在使用已部署的 Web 部署或启动服务器之前存在 应用。
