Erro Extração de texto de imagens com o uso do Tess4j

Boa Noite, estou tentando extrair texto de um imagem usando o Tess4j, mas o seguinte erro tem acontecido:

Error opening data file ./eng.traineddata

Please make sure the TESSDATA_PREFIX environment variable is set to your “tessdata” directory.

Failed loading language ‘eng’

Tesseract couldn’t load any languages!
