How to create a simple 'Hello World' module in Magento? - 404 Error

Question

I'm following the answer to stackoverflow question 576908 but I seem to be getting a 404 Error. Does anyone know what I'm doing wrong. i.e. beginner mistakes?

IndexController:

    <?php
      class MyCompanyName_HelloWorld_IndexController extends         Mage_Core_Controller_Front_Action{
    public function indexAction(){
        echo "We're echoing just to show that this is what's called, normally you'd have some kind of redirect going on here";
    }
}

Config.xml:

<?xml version="1.0"?>
  <config>
 <modules>
    <mycompanyname_helloworld>
        <version>
            0.1.0
        </version>
    </mycompanyname_helloworld>
</modules>
<frontend>
    <routers>
        <!-- the <helloworld> tagname appears to be arbitrary, but by
        convention is should match the frontName tag below-->
        <helloworld>
            <use>standard</use>
            <args>
                <module>MyCompanyName_HelloWorld</module>
                <frontName>helloworld</frontName>
            </args>
        </helloworld>
    </routers>
</frontend>
</config>

In app/etc/modules:

<?xml version="1.0"?>
<config>
<modules>
    <MyCompanyName_Helloworld>
        <active>true</active>
        <codePool>community</codePool>
    </MyCompanyName_Helloworld>
</modules>
</config>

I keep geeting a

404 Error

when I hit the url magento.dev/index.php/helloworld
//NB The url is a virtualhost on my development machine.

I'm running magento 1.8

Make sure to have everything in your config consistently named (e.g. in camel case):

/app/etc/modules/MyCompanyName_HelloWorld.xml

<?xml version="1.0"?>
<config>
<modules>
    <MyCompanyName_HelloWorld>
        <active>true</active>
        <codePool>community</codePool>
    </MyCompanyName_HelloWorld>
</modules>
</config>

/app/code/community/MyCompanyName/HelloWorld/etc/config.xml:

<?xml version="1.0"?>
<config>
    <modules>
        <MyCompanyName_HelloWorld>
            <version>
                0.1.0
            </version>
        </MyCompanyName_HelloWorld>
    </modules>
...

The full call to that would be magento.dev/index.php/helloworld/index/index/.

These should work as well:

magento.dev/index.php/helloworld/index/

magento.dev/index.php/helloworld/

Got it to work for me that way.

This should work. Additionally, do not forget to clear cache or disable them :) — Rakesh Shewale, Jul 24 '15 at 05:51

Try magento.dev/index.php/helloworld/index You passed frontName in url, but didn't pass controller name to the url. BTW, use local code pull for your extensions.

Statichny, that does not work. Also I'm trying to build a community extension hence according to the magento documentation my code should exist in the community directory – acquayefrank Jul 23 '15 at 16:06
