I want to use

OPSystem.getCPLCData(javacard.framework.APDU apdu, short apdu_offset, short cplc_offset, short length)

in install() method. But APDU is not accessible in install method.

Here is my code:

Code: Select all

public static void install(bytes[] bArray, short bOffset, byte bLength){

short apdu_offset = (short)0;
short cplc_offset = (short)8;
short length = (short)2;

OPSystem.getCPLCData(apdu, apdu_offset, cplc_offset length);

}

Does anybody know where I did wrong? Pls help to solve this. Thanks

Because the byte[] in the install method is the global buffer. You will need to defer this call until the process method has been invoked.

Is there any way to get CPLC information in install() method?

It's a little hard to reach your goal. Why do you need it in the install method?
