Tess4j on netbeans

Question

good day,

I am using Tess4j as a wrapper on java to implement Tesseract OCR.

Followed closely to tutorials and guides provided but was returned with the following errors when compiled to scan a sample image:

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

I have already add in then necessary library as well as libtesseract304.dll and gsdll64.dll into the project.

Please refer to my structure below:

Thank you.

There is also a Leptonica dependency, but you don't need to include the source files of Tess4J library as there already is JAR package for it. Check out the example in the Tutorial .
