Take a look here :
http://wiki.openkm.com/index.php/Third- ... ation:_OCR

At administration > configuration parameters did you set the value:
Code: Select all
system.ocr=/usr/bin/tesseract ${fileIn} ${fileOut}

thanks, but i get the same Error with:
Code: Select all
system.ocr=/usr/bin/tesseract ${fileIn} ${fileOut} -l eng  or  system.ocr=/usr/bin/tesseract ${fileIn} ${fileOut}  in the OpenKM.cfg
then i set: hibernate.hbm2ddl=create
in the OpenKM.cfg then it works!

reimport the language sql script

now it works, is the config in the DB stored ?

Yes the configuration is at DB, and almost parameters in OpenKM.cfg have effect on creation, then must be changed from Administration > configuration parameters
