Question

i am absolute beginner to Struts2. I am tying to follow tutorials on struts web site. i followed this tutorial. i have some trouble with it. i created dynamic web project on eclipse. Then i followed the tutorial. However when i run the example i get the following error.

There is no Action mapped for namespace [/] and action name [hello] associated with context path [/Hello_World_Struts_2]. - [unknown location]

i have the following directory structure

And my struts.xml file is

 <?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="true" />

  <package name="basicstruts2" extends="struts-default" namespace="/">

  <action name="index">
    <result>/index.jsp</result>
  </action>

  <action name="hello" class="org.apache.struts.helloworld.action.HelloWorldAction" method="execute">
    <result name="SUCCESS">/HelloWorld.jsp</result>
  </action>

</package>

</struts>

thanks for your responses.

The struts.xml configuration file needs to be on the classpath (as opposed to in WEB-INF).

The linked tutorial assumes a Maven build and states the struts.xml file should go in src/main/resources, which will be included in the classpath in Maven builds. Since you’re ignoring that part, you’ll likely want to put it in the root of your source directory.
