Could not initialize class net.sourceforge.tess4j.TessAPI


#1

The flow I am using on the KNIME Server is using a Tess4J node. The ubuntu tessaract packages are installed with

apt install tesseract-ocr-all libtesseract3

but I still get the error

Tess4J 2:207:67:173
Execute failed: Could not initialize class net.sourceforge.tess4j.TessAPI

What is the problem and how can I solve it?

Hi @M42,

you shouldn’t have to install any libtesseract or so on your system All dependencies should be delivered with our plugin. Which Ubuntu are you running and which KNIME Analytics Platform version? We’ll try to reproduce the problem!

Best,

Christian
