JavaCard OS

Hello everyone,
I want to implement javacardx.biometry.OwnerBioTemplate interface. I wrote the sample code that compile and convert to by JCDK 2.2.2. When i want to load and install to the card by GPShell i get the error code 0x6438 (Imported package not found). But when i comment the " implements OwnerBioTemplate" and "implements SharedBioTemplate", the applet load and install to the card successfully.
the sample code is:

import javacard.framework.*;
import javacardx.biometry.*;
public class bioServerApplet extends Applet implements SharedBioTemplate {

public final static byte CLA = (byte)0xCF;
public final static byte INS_ENROLL = (byte)0x10;
public final static byte MATCH_TRY_LIMIT = (byte)5;
private OwnerBioTemplate impl;

public static void install(byte[] bArray, short bOffset, byte bLength)
{
new bioServerApplet(bArray,bOffset,bLength);
}

private bioServerApplet(byte[] bArray, short bOffset, byte bLength) {
register(bArray, bOffset, bLength);
byte aidLen = bArray[bOffset];
if (aidLen== (byte)0){
register();
} else {
register(bArray, (short)(bOffset+1), aidLen);
}
impl = BioBuilder.buildBioTemplate(BioBuilder.PASSWORD,MATCH_TRY_LIMIT);
}

public void process(APDU apdu){

}

public void enrollData(APDU apdu){
byte []buffer = apdu.getBuffer();
short bytesRead = apdu.setIncomingAndReceive();
impl.init(buffer, ISO7816.OFFSET_CDATA, bytesRead);
impl.doFinal();
//enrollment complete
}


//--- the nethods below implement the SharedBioTemplate interface
public boolean isInitialized(){
return impl.isInitialized();
// return true;
}
public boolean isValidated(){
return impl.isValidated();
//return true;
}
public void reset(){
impl.reset();
}
public byte getTriesRemaining(){
return impl.getTriesRemaining();
//return (byte) 0x33;
}
public byte getBioType(){
return impl.getBioType();
//return (byte) 0x33;
}
public short getVersion(byte[] dest, short offset){
return impl.getVersion(dest,offset);
//return (short) 33;
}
public short getPublicTemplateData(short publicOffset, byte[] dest,
short destOffset,
short length) throws BioException{
return impl.getPublicTemplateData(publicOffset,dest,destOffset,length);
//return (short) 33;
}
public short initMatch(byte[] candidate, short offset, short length)
throws BioException{
return impl.initMatch(candidate,offset,length);
//return (short) 33;
}
public short match(byte[] candidate, short offset, short length)
throws BioException{
return impl.match(candidate,offset,length);
//return (short) 33;
}
}
the OwnerBioTemplate implementation is:

import javacardx.biometry.*;
public class OwnerBioTemplateImpl implements OwnerBioTemplate{

public void init(byte[] bytes, short s, short s1) throws BioException {

}

public void update(byte[] bytes, short s, short s1) throws BioException {

}

public void doFinal() throws BioException {

}

public void resetUnblockAndSetTryLimit(byte b) throws BioException {

}

public boolean isInitialized() {
return true;
}

public boolean isValidated() {
return true;
}

public void reset() {

}

public byte getTriesRemaining() {
return 0x33;
}

public byte getBioType() {
return 0x33;
}

public short getVersion(byte[] bytes, short s) {
return 33;
}

public short getPublicTemplateData(short s, byte[] bytes, short s1, short s2) throws BioException {
return 33;
}

public short initMatch(byte[] bytes, short s, short s1) throws BioException {
return 33;
}

public short match(byte[] bytes, short s, short s1) throws BioException {
return 33;
}
}

Anyone can help me to solve my problem?

I have done test with your project in JCIDE, and the project can be downloaded and installed in JCIDE simulator successfully. it can run without any problem. So I guess maybe your real card doesn't support some function.

From your description, please make sure your card implements package javacardx.biometry. javacardx package is Extension packages, Not all card implements these functions.

Thanks trantino for your reply.
I tested my code in netbeans simulator (cjcre.exe) but it couldn't load my applet too. My card is a javacard 2.2.2 and i could load a javacard 2.2.2 hello world applet. javacardx.biometry package is a interface and my applet wants to implement it. I must mention that when i comment "implements SharedBioTemplate" my applet load to card successfully.
Do you mean my card doesn't support javacardx.biometry interfaces? because i want to implement biometric package not card.

thanks for reply. javacardx.biometry package has some interface and i want to implement it not card.

very thanks for compiling my code. I have to test my code by JCIDE.

I tested uploaded JCIDE project by JCIDE. When i compile your project i get error "package javacardx.biometry does not exist";
what i am missing?

Hi,

The error you got is just because the java card kit version is wrong. Follow the steps below to change JCKit version in JCIDE to jc 2.2.2, the project will be complied successfully.

From the menu, select " Build-> Property ", a dialog box "Property Sheet" will pop up. Click "Local JCKit Configuration" in the side bar, and unfold "JCKit Option" and for first item "Java Card kit version", select "java_card_kit-2_2_2" from dropdown list.

Thank you tarantino,
You are right. can you answer another question. hasn't JCIDE any facilities to load two applet on simulator simultaneously? (To find out can i call javacardx.biometry interfaces which i implemented in second applet)

In JCIDE, select " Debug-> Run or Debug Configuration ", click "Add Cap File", select the applet you want to download first and then click button "Up " to adjust the downloading order. After this, click "Debug" to debug your applet. The applets will be downloaded according to the order you arranged.
