B4J Question Tesseract OCR Error

[Philip Chatzigeorgiadis]

I am following this tutorial.

How to OCR image text

1.Download the following .jar files: lept4j-1.19.0.jar slf4j-api-1.7.32.jar jai-imageio-core-1.4.0.jar jna-5.14.0.jar tess4j-5.10.0.jar Place then in addLibs ( or whatever) Refer to them with #AdditionalJar: 2.Download Tesseract-OCR and place the folder in Objects 3. Use the following inline...

I have this code

The card1.png file is in the objects folder.
All additional jar files are in the Additional Libraries folder (I had to add #AdditionalJar:slf4j-simple-1.7.32.jar, to get rid of an initial error).

I am not sure which folder from tesseract-main download I should put into the Objects folder or how to reference it. The instructions in the tutorial link above mention "Download Tesseract-OCR and place the folder in Objects" but the inline java code mentions the tessdata folder.
For now I have the tessdata folder (a subfolder in the tesseract-main download) copied in the Objects folder and referencing it per above (in the inline java code). But I have made various combinations. I always get the same error (I have no idea what that garbled string in the error might be):
