It doesn't work in JAVA.
please check. It says there is no file name. Any reason?

import net.sourceforge.tess4j.*;
import java.awt.image.BufferedImage;
 
Tesseract ocr;
BufferedImage img;
PImage pimg;
String res, show;
int idx;

void setup() {
  ocr = new Tesseract();
  ocr.setDatapath(dataPath(""));
  ocr.setLanguage("ssd");
  pimg = loadImage("a4.jpg");
  img = (BufferedImage) pimg.getNative();
  show = "";
  idx = 0;
  try {
    res = ocr.doOCR(img);
    //   println(res);
  } 
  catch (TesseractException e) {
    println(e.getMessage());
  }
  frameRate(25);
}

error message

It is recognized only by putting a number in front of the 7-segment number.

Environment :

1. Works on tess4j-4.0.0.
2. ssd.traineddata

The problem is that the number must be entered arbitrarily in front of it to be interpreted.
It is not immediately recognized as a 7-segment number.
Why?

Test of a small sample of real life images gives better results with the older 7seg.traineddata. Unfortunately I have deleted the source training_text for the same. Customizing the training text and fonts based on the requirements as well as preprocessing the images to reduce the gaps will lead to better recognition.
