Запуск MALLET в Java

Я пытаюсь запустить Mallet в Java и получаю следующую ошибку.

Couldn't open cc.mallet.util.MalletLogger resources/logging.properties file.
Perhaps the 'resources' directories weren't copied into the 'class' directory.
Continuing.

Я пытаюсь запустить пример с сайта Mallet (http://mallet.cs.umass.edu/topics-devel.php). Ниже мой код. Любая помощь приветствуется.
