Admittedly thinking while feeling feverish is slightly impaired, but it took me a little while to figure this one out… Trying to integrate ZF 1.11 with Doctrine2 to as per this article, I was trying to be a smart-ass and use TSResourceEntityManager instead of the ugly looking TSResourceEntitymanager.
Unfortunately all this got me was this very unhelpful error:
Zend_Application_Bootstrap_Exception with message Resource
matching <strong>"entityManager"</strong> not found
It turns out that although the case of the resource name in the application.ini dosn’t really matter the class name does not like mixed case. So had to settle with TSResourceEntitymanager as the plugin name.
