請(qǐng)大家都幫忙解答一下，百度了好久也沒(méi)改出來(lái)

我的Strust文件源代碼：

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

"http://struts.apache.org/dtds/struts-2.3.dtd">

? ? <package name="default" namespace="/" extends="struts-default">

? ? ? ? <action name="helloworld" class="com.imooc.action.HelloWorldAction">

? ? ? ? ? ? <result >/result.jsp </result>

? ? ? ? </action>

? ? </package>

</struts>

報(bào)的錯(cuò)誤為：

Caused by: Action class [com.imooc.action.HelloWorldAction] not found - action - file:/E:/na/mystrust/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/HelloWorld/WEB-INF/classes/struts.xml:10:77
