java.lang.NoClassDefFoundError: net/sourceforge/tess4j/TesseractException

I try to do an ocr application for Mirth with Java and Tesseract.I export the project in jar file and call in Mirth with Javascript that did a hello world application.I believe that I add the jar files right way.However I have a problem in Java OCR,so I get this error,

ERROR (com.mirth.connect.connectors.js.JavaScriptDispatcher:193): Error evaluating JavaScript Writer (JavaScript Writer "RTF>DCM" on channel b469e5af-a78d-41ca-86a0-a7b507799a4d). java.lang.NoClassDefFoundError: net/sourceforge/tess4j/TesseractException

Thank you so much for your helps.

You have to download the Tess4J.jar and add it to the classpath. This jar contains the missing class net/sourceforge/tess4j/TesseractException
