在Java中创建Leadtools的AutoFormsEngine实例

1 周，4 日 Questions & Answers 29

我试图在Java应用程序中使用Leadtools的“Forms Recognition and Processing SDK”。创建RasterCodecs、OcrEngine（OcrEngineManager.createEngine）、BarcodeEngine和DiskMasterFormsRepository的实例没有问题。我需要创建的最后一件事是AutoFormsEngine的一个实例，但是我得到了下面的异常

leadtools.RasterException: javax/xml/bind/DatatypeConverter
