Unable to load library 'libtesseract302': The specified module could not be found

Question

All - I am trying to use tess4j in my Java project. I have followed the following steps -

1. copied the jar files from /dist and /lib as a external jar files while creating the project.
2. Copied the /tessdata and libtesseract302.dll to the project root and even in src folder of the project.

3. Below is the code(tess4j example code in sf) -

   import java.io.File;
   import net.sourceforge.tess4j.*;
   
   public class ReadingImage {
   
       public static void main(String[] args) {
           File imageFile = new File("C:\\Documents and Settings\\T9SAUR\\My Documents\\Downloads\\Tess4J-1.1-src\\Tess4J\\eurotext.tif");
           Tesseract instance = Tesseract.getInstance();
           try {
               String result = instance.doOCR(imageFile);
               System.out.println(result);
           } catch (TesseractException e) {
               System.err.println(e.getMessage());
           }
       }
   }
   

yet my code is giving the error. As per the other post on the same topic, I checked the JVM version (32 bit) and eclipse version(32 bit). Please let me know, where I went wrong.

Answer 1

If you are using Eclipse to launch, then you need to specify the location of native libraries associated with the Tesseract jar. See How to set the java.library.path from Eclipse

Answer 2

If you are using JNA (or your framework/library uses JNA), in this case tess4j does uses

Try this

-Djna.library.path=${workspace_loc:/ocr-tess4j-example}/dll/win32-x86-64

or

-Djna.library.path=path/to/dlls
