i have to search in document stored in databases,among these documents is images,so i used tess4j to read this images. in windows with eclipse the project works fine with tess4j ,also if i deploy application in tomcat 6.35 in windows7 the projects works fine and i can search correctly with tess4j. sous windows 1) i add the jar files in tomcat lib/shared 2) the tessdata and dll file are in repository and i call them in the project.
in linux environment i do the same things and the first error that i get is
- Native library (linux-x86/libtesseract.so) not found in resource lib/shared/*
i add the libtesseract.so and the tessdata to this path and now i get an other error:
