Hi! I am new with Sikuli and Tesseract OCR; I like to recognise text using Sikuli OCR and Jython as
'strLast = OCR.readWord(regLastFallenNumber)', or 
'strLast = regLastFallenNumber.text()'

I am running  Sikuli 2.0.4-2020-03-14_08:01 / WINDOWS 6.1 (=Win7) 64bit / java version "1.8.0_251"; Sikuli automation works.

It fails with this for the OCR class call:
"...
) raised: Traceback (most recent call last):
  File "<string>", line 14, in <module>
	at org.sikuli.script.TextRecognizer.getTesseractAPI(TextRecognizer.java:83)
	at org.sikuli.script.TextRecognizer.doRead(TextRecognizer.java:350)

java.lang.NoClassDefFoundError: java.lang.NoClassDefFoundError: Could not initialize class net.sourceforge.tess4j.Tesseract1"

So, I researched int internet and found about Tesseract that it "Windows: Works out of the box". So, why then the above message? 

By the way, here the Jython I was using in the Sikuli IDE - also not sure that I am not mixing up concepts there...
    # OCR configuration
    import org.sikuli.script.TextRecognizer as STR        # switch on the OCR feature
    OCR.reset()
    optMySet = OCR.Options()
    optMySet.oem(3)
    optMySet.psm(8)
    optMySet.asWord()
    optMySet.language("eng")
    #optMySet.smallFont()
    optMySet.variable("user_defined_dpi", "112")
    STR.reset()
    #print optMySet

    Settings.OcrTextRead = True
    
    regLastFallenNumber = Region(425,292,48,21)
    regLastFallenNumber.highlight(1)
    strLast = OCR.readWord(regLastFallenNumber)
    #strLast = regLastFallenNumber.text()
    print strLast

Thanks a lot for your help :)

Simon
