No input source set error exception Tess4J

Question

I just downloaded Tess4J from http://tess4j.sourceforge.net/ and imported it in netbeans. Code is running but when i enter URL for image and try to convert it i'm getting an error.

My code:

public static void main(String[] args) {
    File imageFile = new File("http://www.example.com/example-image.png");
    Tesseract instance = Tesseract.getInstance(); //

    try {

    String result = instance.doOCR(imageFile);
    System.out.println(result);

    } catch (TesseractException e) {
    System.err.println(e.getMessage());
    }
}

Output error:

02:51:36.251 [main] ERROR net.sourceforge.tess4j.Tesseract - No input source set!
java.lang.IllegalStateException: No input source set!

Anyone else experienced something like this before? I found 3 more similar topics on stackoverflow but they did not help me..

Answer 1

Your input file location is not a valid , try a valid file location or try testing with local file location.
