    Hi, I do not know which Java package has the classes metioned on the link, but below is some sample code that worked for me:

    String url = "apdu:0;target=[javacard_application_id]";
    byte [] data = new byte[] { /*will be sent to javacard application*/ };
    APDUConnection ac = (APDUConnection) Connector.open(url); // from package javax.microedition.apdu, JSR 177

    data = ac.exchangeAPDU(data); // after this line 'data' will hold the response
    if (data[0] == 0x61) { // process completed, normal processing
    }
