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文件配置了打印机。 当我运行healthCheck.bat文件时，它在控制台中显示此错误。

操作系统：Windows Server 2003 JDK：1.5

缺少哪些库文件？

请帮帮我。 提前谢谢。

2 个答案:

答案 0 :(得分：0)

从技术Java的角度来看：DLL和Java库在其他位置丢失或预期。

从应用程序的角度来看：由于你有一个安装例程（手动）和adk附带的一些批处理文件，我很确定你应该再次阅读文档。我猜你错过了一步或改变了安装路径，因此批处理文件看错了位置。

答案 1 :(得分：0)

简答：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。

完整答案：如果您要安装EPSON Java POS，请打开（Program Files）\ EPSON \ JavaPOS \ SetupPOS \ CheckHealth \ checkhealth.bat。检查哪个jre用于启动CheckHealthTest.jar。复制jp_co_ 从jre \ bin到Windows \ System32 \的epson_upos_firm_FirmNativeAccess.dll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");
    }
}
