Failed download of Tesseract's 'eng' language couldn't load languages! List of available languages (2): deu osd IMHO is not a bug upstream, because tesseracts ( say: qgt; each version of Tesseract has its own language data that you need to get. You should get and install trained data for English (eng) and osd. Make sure Tesseract is aware of these two files (and other trained data you've installed) with this team: tesseract --list-langy. We only found the bug in Windows. The problem can be detected at several points in the application: the OCR zone does not work. The process of extracting text fails in PDF or image documents and you can't find them from the search engine. The application raise an error like: 2018-11-22 15:46:09,835 [http-nio-0.0.0.0-8080-exec-10] [dms.support1] WARN com.openkm.util.ExecutionUtils - Abnormal program termination: 1 2018-11-22 15:46:09,836 [http-nio-0.0.0.0-8080-exec-10] [dms.support1] WARN com.openkm.util.ExecutionUtils - CommandLine: [C:\tomcat-8.5.24\extras\Tesseract-OCR-3.05.02\tesseract.exe, C:\tomcat-8.5.24\temp\okm6648884784480326422.jpg, C:\tomcat-8.5.24\temp\okm6036470490263572358] 2018-11-22 15:46:09,836 [http-nio-0.0.0.0-8080-exec-10] [dms.support1] WARN com.openkm.util.ExecutionUtils - STDERR: Error opening data file C:\tomcat-8.5.24\extras\Tesseract-OCR\tesseract.exe/tessdata/eng.traineddata make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your</tesseract> </tesseract> </tesseract> Catalog. Failed download of Tesseract's 'eng' language couldn't load languages! Couldn't initiate tesseract. The reason the tesseract OCR engine doesn't work is because there are missing or incorrect variable environments TESSDATA_PREFIX values.

Failed Tesseract language download couldn't download any language, and Tesseract's failed 'chi_tra' language could not download languages! A deadly bug has been discovered in java Runtime: Tess4J works well with any language data on Windows and Linux. We don't have an OS X system to perform testing, so it will depend on users to perform. I suggest you download the source of JNA and step through it to debug the issue. Failed download of the language 'eng' Tesseract could not download any, Unsuccessful download language 'eng' Tesseract could not download any languages! #82. Closed tongues! My Mac OS development environment, Java 8 I've never used a library as complex as this one, I use Linux Java. Well I managed to do tess4j work and then copied all the original packages and libraries in my project, everything seemed fine, but when I was trying to work I get bugs Tesseract can't download any languages!, Tesseract.doOCR (Tesseract.java:288).
