Helper classes expect a class *prefix*. Since yours does not have a
prefix, that's what's causing the issue. Try the following:
* Rename your helper to 'My_Help'
* Then register it:
Zend_Controller_Action_HelperBroker::addPath($path, 'My');
This tells the helper broker to look for them at the given path, and
assume that they have the prefix 'My_' (you don't need the
underscore when registering; it does that for you).
* In your action controller, try this:
$helper = $this->_helper->getHelper('help');
This will look for action helpers that end with 'Help', and likely
find your 'My_Help' class and create that helper.
