Tesseract - The specified module could not be found

Question

In my Java application, I want to extract text from images. I downloaded Google's Tesseract OCR and installed it in my Windows XP machine. I followed the tutorial Tess4J - JNA wrapper for Tesseract , unfortunately this error came up:

Exception in thread "main" java.lang.UnsatisfiedLinkError: The specified module could not be found.
