MFStandardExample problem

[joli_u]

Hi!

I just updated my phone to firmware 5.11 but the MFStandardExample midlet doesn't work on the phone. I always get a Java.lang.SecurityExeption.

I tracked it back to this line:
conn = (MFStandardConnection) Connector.open(internalUrl);

i checked if the internalUrl is right and displayed it on the phone, it seems correct: nfc:rf;rype=mf;mode=internal


screen.append("Connecting to internal tag.\n");
String internalUrl = System.getProperty("internal.mf.url");
screen.append(internalUrl);
screen.append("Connected to internal tag.\n");
//exception gets thrown here:
conn = (MFStandardConnection) Connector.open(internalUrl);
screen.append("Connected to internal tag.\n");


Do i need special security settings to connect to the internal Mifare card? Or what else have i done wrong?

The example works perfectly in the emulator with an external reader (Omnikey CardMan5321) plus a mifare 4k card.

thanks in advance,
joli

This is because your midlet isn't signed. Without a signed midlet you will be unable to access any part of the secure element.

Eventhough the manual says that you need to have your midlet signed, the code you mention works for me without the midlet being signed. I also have firmware 5.11. I must say that I was suprised that it worked, without signing the midlet.
