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

Question

我尝试使用 Java 和 Tesseract.I 为 Mirth 做一个 ocr 应用程序，将项目导出到 jar 文件中，然后使用 Java 脚本调用 Mirth，它做了一个 hello world application.I 相信我添加了 jar 文件 way.However 我在 Java OCR 中遇到问题，所以我得到这个错误，

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

            ITesseract instance = new Tesseract();

            try {
                String result = instance.doOCR(imageFile);

                int i=result.indexOf("Numarasn: ");
                int j=result.indexOf("Tel No:");
                int k=result.indexOf("Bilgllendirme Tarihl:");

                Tc = result.substring(i+10, i+22);
                phone = result.substring(j+8,j+23);
                date = result.substring(k+22,k+32);


            } catch (TesseractException e) {
