这是我struts config file的： 我的项目的根是StrutsProject。
<?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">
<struts>
<constant name="struts.devMode" value="false" />
<package name="first" namespace="/helloworld" extends="struts-default">
<action name="HelloWorld" class="com.abc.actions.HelloWorldAction">
<result name="SUCCESS">/pages/login.jsp</result>
</action>
</package>
</struts>
我正在尝试访问以下 URL：
http://localhost:8080/StrutsProject/helloworld/HelloWorld.action
我收到以下错误：
There is no Action mapped for action name helloworld. - [unknown location]
