使用Java和tesseract，tess4j进行板识别

Question

编译程序时遇到问题。代码本身没有错误。

程序代码：

    package plate;

import java.io.File;

import net.sourceforge.tess4j.Tesseract;

public class OcrReader {

    public static void main(String[] args) throws Exception {
        String inputFilePath = "C:\\Users\\Me\\eclipse-workspace\\platerecognition\\picture.tif";
        Tesseract tesseract = new Tesseract();

        String fullText = tesseract.doOCR(new File(inputFilePath));
        System.out.println(fullText);
    }
    }

运行程序后的错误：

  Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/jna/Pointer
    at plate.OcrReader.main(OcrReader.java:11)
