calling a get-function in Zend Framework

This is probably an easy question. If I call Cities::getName(), I get the following error. I'm probably using this the wrong way, but I don't see what's wrong. In Eclipse, the method fetchRow does appear.

Fatal error:  Uncaught exception 'Zend_Controller_Action_Exception'
with message 'Method "fetchRow" does not exist and was not trapped in __call()' in D:\web\test\library\Zend\Controller\Action.php:478
