我们正在使用 Tess4J/Tesseract 在 web 应用程序上执行 OCR。在 Windows 上一切正常，但是当部署在 Linux 机器上时，程序崩溃，杀死 glassfish 进程并输出一个转储文件：hs_err_pidXXXXX.log.

tesseract 命令可以正常工作并将图像正确转换为文本。我们已经尝试了LC_NUMERIC解决方案，但仍然无法正常工作。

我们的 Tesseract java 代码是这样的

File file; // ...
boolean hOcr; // ...
Rectangle rec; // ...
OcrResult result;
//Tesseract instance = Tesseract.getInstance();
Tesseract1 instance = new Tesseract1();
try {
    instance.setHocr(hOcr);            
    ImageIO.scanForPlugins();
    String res;
    if (rec == null) {
        res = instance.doOCR(file);
    } else {
        res = instance.doOCR(file, rec);
    }
    result = new OcrResult(res, 0, true);
} catch (TesseractException e) {
    log.error("error tesseract", e);
    // process error
} catch (Error e) {
    log.error("error tesseract", e);
    // process error
}

我们的规格

  • 正方体 3.02.02
  • 苔丝4J
  • CentOS 6.4
  • Java 1.7
  • 玻璃鱼 4.1

有没有人有什么建议？

事实证明这是多种因素的结合：
