If you have an applet on javacard. the javacard cos perhaps had processed the select command and the command is err or no compatible withe the standard special. So the applet can't receive the select command and the response of this command cannot be send to the off-card.
If you have an applet and the applet receive the select command. the applet can put the response data in the function:select() or process(). These functions are standard API. eg:
public void process(APDU apdu) {
if (selectingApplet()) {
byte[] apduBuf = apdu.getBuffer();
short rspLen = (short) selectResponse.length;
Util.arrayCopyNonAtomic(selectResponse, (short) 0, apduBuf, (short) 0, rspLen);
apdu.setOutgoingAndSend((short) 0, rspLen);
return;
}
...
}
