Yes, classification in eCognition is not an easy task. You can do a supervised classification like in ERDAS or ENVI, by selecting image objects samples for each class to apply Standard Nearest Neighbour (StNN). After you obtain a classification image, you can do a refinement (or adjustements) by using tresholds to better separate classes, by their shapes, position to other calsses and more other features. (this is called a "rule-set") So, eCognition is a good software to make classification, but it is not so simple like: press a button and pac-pac > you have the best classification image !
