Struts 2 URL error

This is my struts config file: The root of my project is 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>

I am trying to access the following URL: http://localhost:8080/StrutsProject/helloworld/HelloWorld.action

I am getting the following error:

There is no Action mapped for action name helloworld. - [unknown location]

Please help, Siddharth

Is your JSP file location is correct??

/pages/login.jsp

Or It should be

/WEB-INF/pages/login.jsp
