Shareable Interface--Can arrays be passed from client applet to server app
Hi,
Not sure whether this topic is already discussed or not. I have 2 applets communicating each other through Shareable Interface. I want an array of data which is there in 'client Applet' to be available in 'Server applet'. I will pass this array through a function ( there in Interface) which accepts array as arguments.
I just tested the similar scenario, and I found the array object is null at server side, any suggestions?
Thanks in advance for reply

Here is the code of an client applet
/**
* Method Name : Client
* Returns : void
* Parameters : byte[], short, byte
* Description : Constructor - intializes the PIN objects, emv, bank record
* objets etc
*/
public Client(byte[] buffer, short offset, byte length) {
//super.process(object);
// Get the reference to GSM 3.19 Registry object
reg = ToolkitRegistry.getEntry();
// Add menu items to GSM 3.19 Registry
reg.initMenuEntry(menuLevel1, (short) 0,(short) menuLevel1.length, PRO_CMD_SELECT_ITEM, false,(byte) 0, (short) 0);
m_PIN = new OwnerPIN( (byte) PIN_TRY_LIMIT, (byte) MAX_PIN_LENGTH);
Util.arrayFillNonAtomic(temp_APDU,(short)0,(short)(temp_APDU.length & 0x00FF),(byte)0x30);
}
/**
* Method Name : install.
* Returns : void.
* Parameters : byte[], short, byte. [i.e AID of an applet, start offset, AID Length ] throws : ISOException.
* Description : called by JCRE while creating the Applet instance .
*/
public static void install(byte[] tmpBuf, short offset, byte length) throws ISOException {
// Create the Javacard applet
Client client = new Client(tmpBuf, offset, length);
// Install Applet onto Javacard 2.1 System
client.register();
}
/**
* Method Name: process.
* Returns : void
* Parameters : APDU apdu - Holds theCommand APDUs sent from Off-card

*/
public void process(APDU apdu) {
try {
if (selectingApplet()) {
temp_APDU[0] = (byte)0x31;
temp_APDU[1] = (byte)0x32;
temp_APDU[3] = (byte)0x33;
return;
}
switch(apdu.getBuffer()[1]) {
// specific APDU for this applet to configure the MenuTitle from SelectItem
case (byte)0x46:
/*Util.arrayCopy(apdu.getBuffer(),(short)0x0005,menuTitle,(short)0x0000,

break;

}
} catch(Exception exception) {

}
public boolean select() {
return true;
}

if(respHandler.getGeneralResult() == (byte) 0x00)
callServerMethod();
break;

}
private void callServerMethod() {
try {

//byte b = (byte)shareable.verifymChekPin();
display(temp_APDU, (byte)0, (byte)0x03);
//byte b = (byte)shareable.testArray(server_AID, (byte)0, (byte)(server_AID.length & 0x00FF));
byte b = (byte)shareable.testArray(temp_APDU, (byte)0, (byte)(0x02 & 0x00FF));
//byte b = (byte)shareable.testArray(apdu);
if(b == 0x00)
display(Success,(short)0,(short)Success.length);
else if(b == (byte)0x01)
display(One_exception,(short)0,(short)One_exception.length);
else if(b == (byte)0x02)
display(Success,(short)0,(short)0x02);
} catch(Exception exception) {
}
}
Just want to know how to fill the data in "temp_APDU" array so that it is available in server applet?
