java pos健康檢查問題

Question

我爲通過以太網連接的epson打印機TMU230安裝了java pos adk（1.11.18）。我通過運行setupPos.exe文件來配置打印機。 當我運行healthCheck.bat文件時，它在控制檯中顯示此錯誤。

操作系統：Windows Server 2003 JDK 1.5

的庫文件丟失？

請幫幫我。 在此先感謝。

Answer 1

從技術上的Java角度來看：一個DLL和一個java庫可能在一個不同的位置丟失或期望。

從應用程序的角度來看：由於您有一個安裝例程（手動）和adk附帶的一些批處理文件，我非常確定您應該再次閱讀文檔。我想你已經錯過了一個單獨的步驟或者更改了安裝路徑，以便批處理文件查看錯誤的位置。

Answer 2

簡短的回答：檢查你的java.library.path（的System.out.println（System.getProperty（ 「的java.library.path」） 確保有jp_co_ epson_upos_firm_FirmNativeAccess.dll路徑

。

Long答：如果您正在安裝EPSON Java POS，請打開（Program Files）\ EPSON \ JavaPOS \ SetupPOS \ CheckHealth \ checkhealth.bat。檢查啓動CheckHealthTest.jar時使用的是哪個jP_co_ epson_upos_firm_FirmNativeAccess.dll jre \ bin到Windows \ System32 \或java.library.path中的任何路徑

要測試的示例程序

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"); 
    } 
}
