在 Java 中创建 Leadtools 的 AutoFormsEngine 实例

Question

我正在尝试在 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 的实例，但我得到了下面的异常。

我自己找到了解决方案。显然 Leadtolls 不适用于 Java SDK 14，而这正是我使用的。我降级到 Java SDK 8 并且它工作正常。
