Java POS 健康检查返回“java.lang.UnsatisfiedLinkError”

发布于 2024-12-05 10:27:11 字数 7418 浏览 2 评论 0原文

我为通过以太网连接的 Epson 打印机 TMU230 安装了 Java pos adk (1.11.18)。我通过运行 setupPos.exe 文件配置打印机。 当我运行 healthCheck.bat 文件时，它在控制台中显示此错误。

缺少哪些库文件？

I installed the Java pos adk (1.11.18) for Epson printer TMU230 connected through ethernet. I configured the printer by running setupPos.exe file.
When I run the healthCheck.bat file it is showing this error in console.

从 Java 技术角度来看：DLL 和 java 库要么丢失，要么位于不同的位置。

从应用程序的角度来看：由于您有安装例程（手册）和 adk 附带的一些批处理文件，我非常确定您应该再次阅读文档。我猜您错过了一个步骤或更改了安装路径，因此批处理文件查看了错误的位置。

From a technical Java perspective: a DLL and a java library are either missing or expected at a different location.

From an application perspective: As you have an installation routine (manual) and some batch file shipped with the adk, I'm pretty sure that you should read the documentation again. I guess that you've missed a single step or changed installation paths so the batch file looks at wrong locations.

简短回答：检查 java.library.path (System.out.println(System.getProperty("java.library.path")。
确保有 jp_co_
路径中的 epson_upos_firm_FirmNativeAccess.dll。

长答案：如果您要安装 EPSON Java POS，请打开 (Program Files)\EPSON\JavaPOS\SetupPOS\CheckHealth\checkhealth.bat。检查使用哪个 jre 来启动 CheckHealthTest.jar。复制 jp_co_
epson_upos_firm_FirmNativeAccess.dll 从 jre\bin 到 Windows\System32\ 或 java.library.path 中的任何路径

要测试的示例程序

public class Test {

    public static void main(String[] args) {      
        System.out.println(System.getProperty("java.library.path"));
        System.loadLibrary("jp_co_epson_upos_firm_FirmNativeAccess");
    }
}

Short Answer: Check you java.library.path (System.out.println(System.getProperty("java.library.path").
Make sure there is jp_co_
epson_upos_firm_FirmNativeAccess.dll in the path.

Long Answer: If you are installing EPSON Java POS, open (Program Files)\EPSON\JavaPOS\SetupPOS\CheckHealth\checkhealth.bat. Check which jre is using to start CheckHealthTest.jar. Copy the jp_co_
epson_upos_firm_FirmNativeAccess.dll from jre\bin into Windows\System32\ or any path in java.library.path

Sample Program To Test

public class Test {

    public static void main(String[] args) {      
        System.out.println(System.getProperty("java.library.path"));
        System.loadLibrary("jp_co_epson_upos_firm_FirmNativeAccess");
    }
}
