[2.0.5] Linux: Tesseract Tess4J Dont Work

Asked by Oleg

Hello. I use SikulixIDE-2.0.5-lux.jar, jre1.8.0_401, java version 1.8.0_401, Java HotSpot(TM) 64 Bit Server VM (build 25.401-b10, mixed mode) on Linux. Tesseract installed. Tess4J downloaded but don't know how to install. My script is:

from sikuli import *
s = Image.create("picture.png")
print(s.text())

This does not work. Writes:
[error] java.lang.UnsupportedOperationException: The BROWSE action is not supported on the current platform!
Perhaps I did not link the Tess4J to the Sikuli. How to do it?
Help me please.

how to make Tesseract ready for Sikulix:
https://github.com/RaiMan/SikuliX1/wiki/macOS-Linux-‐-Support-libraries-for-Tess4J-Tesseract-4-OCR

No need for Tess4J - is in the package already.

In a main script
from sikuli import *
is not needed, only in subs.

s = Image.create("picture.png")
print(s.text())
is corrrect and works for me (tested on Windows)

Without
from sikuli import *
I get another error:
[error] java.lang.NoClassDefFoundError ( java.lang.NoClassDefFoundError: Could not initialize class net.sourceforge.tess4j.Tesseract1 )
[error] --- Traceback --- error source first
line: module ( function ) statement
3: main ( <module> ) print(s.text())

If I type tesseract -v :
tesseract 4.0.0
 leptonica-1.76.0
  libgif 5.1.4 : libjpeg 6b (libjpeg-turbo 1.5.2) : libpng 1.6.28 : libtiff 4.0.8 : zlib 1.2.8 : libwebp 0.5.2 : libopenjp2 2.1.2

If programm started with option -v and i run one line "print(s.text())" then write:

Why "using Tesseract 4.1.x."? Perhaps the problem in version of tesseract? Write [debug] OCR: start: Tess4J 4.5.4 using Tesseract 4.1.x. , but I have tesseract 4.0.0
