如何以編程方式使用java或java Applet加載Java卡applet（.cap文件）

Question

如何使用java或java Applet以編程方式加載Java卡applet（.cap文件）。

I'm trying to install an applet (.cap file) into a smart card. I read that can be done using APDU. I created my applet using Netbeans. 

我已經創建使用我的小程序，我現在想安裝/加載到物理智能卡NetBeans中.CAP文件。我希望能夠協助我如何或使用什麼工具將.CAP文件安裝到卡上。另外，我還需要安裝到卡中。 而我有兩個設備HID OMNIKEY CARDMAN 5x21 1和HID OMNIKEY CARDMAN 3x21 0 java智能卡讀卡器，我也有兩種卡，如Java卡（J2A ..或J3A ..）和基礎卡（ZC ..） 注意：我不想使用任何第三方軟件或工具 而我的小程序代碼是： 包smartCard; import javacard.framework。*;

有了這些信息誰能幫我建立正確的APDU將我的cap文件安裝到真正的智能卡中？ 謝謝。

我也堅持同樣的問題，我找到了我將與你分享的解決方案。

請遵循以下步驟：

1：請點擊此處下載gp.exe

2：打開Windows命令提示符。

3：轉至location/directory其中包含gp.exe文件。

4：現在將您的讀卡器連接到機器並將卡插入讀卡器。

5：比鍵入

cmd > gp.exe 
cmd > gp –help 

如果一切正常比你會看到列出的所有支持的命令有：

一個cmd > gp –info 這將列出所有的卡信息。

bcmd > gp –list 這將列出安裝在卡上的所有小程序。

c：cmd > gp –delete AID(of applet) 這將刪除安裝的小程序。

d：cmd > gp –install xyz.cap（複製.cap文件在同一目錄下gp.exe被放置在地方xyz.cap選擇） 這會安裝小程序到物理智能卡。

現在您需要APDU命令與卡進行通信。
