[TYPO3-english] Getting categories from hook class

Hi there,

im writing an extension in which I need to get the details of a
category from a function which is called as a hook.

A bit of reading and a bit of testing I came to this solution:

/** @var $objectManager \TYPO3\CMS\Extbase\Object\ObjectManager */
$objectManager = GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Object\\ObjectManager');

/** @var $orderRepository \GeorgRinger\News\Domain\Repository\CategoryRepository */
$categoryRepository = $objectManager->get('TYPO3\\CMS\\Extbase\\Domain\\Repository\\CategoryRepository');

$category = $categoryRepository->findOneByTitle('categoryname');

But i get this message:

#1247602160: Table 'typo3.tx_extbase_domain_model_category' doesn't exist

I am wondering how this name of this table is defined. I thought it
would have to be 'sys_category'.

Can anyone explain this to me or help me to debug this?
