    Accessing MiFare 4k tag from Midlet

    Hi,

    I'm currently working with a Nokia 6131NFC mobile phone. I'm trying to access MiFare in Read and Write.
    I used the code provided by the SDK and that I also found here on this forum:

    String uri = System.getProperty("internal.mf.url");
    MFStandardConnection mfConn = (MFStandardConnection) Connector.open(uri);

    But when I deploy the midlet on the phone I get a No Class Def error.
    It seems that Nokia is supposed to release a fix for the phone firmware that resolves this problem. I have already used Nokia' s Software Updater to update the firmware but it seems that there is no available updates.

    Has anyone already had the problem? Does Nokia provide support for that?
    Is there any other way to access the MiFare 4k tag from a Midlet??

    Thanks in advance for your help and feedback.
    Cheers

    JB

    Hi,

    Just want to clarify that I'm talking about the internal MiFare tag located in the Secure Element.
    Has someone already experienced this error message??

    Many thanks

    JB
