Question

我想使用Wildfly 11和Tess4j库。我有一个简单的程序，它正在运行。

    public static void main(String[] args) {
    File imageFile = new File("myPath.pdf");
    ITesseract instance = new Tesseract(); // JNA Interface Mapping
    instance.setDatapath("myPath/tessdata");
    instance.setLanguage("deu");

    System.setProperty("jna.encoding", "UTF8");
    instance.setOcrEngineMode(TessAPI.TessOcrEngineMode.OEM_DEFAULT);

    try {
        String result = instance.doOCR(imageFile);
        System.out.println(result);
    } catch (TesseractException e) {
        System.err.println(e.getMessage());
    }
}

->如果我尝试在Eclipse中以“ JAVA应用程序”运行程序，则该方法有效，但是如果我尝试从Wildfly应用程序服务器执行该程序，则会出现错误：

有什么想法吗？我正在使用tess4j 4.3.0，并且还安装了Ghostscript ... 单个JAVA应用程序和Wildfly服务器之间可能会有所不同。

Answer 1

它抱怨语言环境。启动Java应用服务器时，需要将其设置为C：

export LC_ALL=C
