    Can't start NFC manager

    Hey all,

    I can't start the NFC manager in the emulator. If I choose the option "Start NFC Manager" nothing happens. If I go to:

    C:\Nokia\Devices\S40_Nokia_6212_NFC_SDK\NFCManager

    and try to start nfcmanager.exe nothing happens. Also running it in cmd.exe gives no output.

    If I try to run my MIDLet from netbeans I get this exception:

    Exception in thread "SharedEmulatorInvoker.PreferencesMonitor" java.lang.NullPointerException
    at com.nokia.phone.sdk.SharedEmulatorInvoker$PreferencesMonitor.run(Unknown Source)
    at java.lang.Thread.run(Unknown Source)

    I don't know if this is relevant but before yesterday I was running JDK 1.5 on my machine and it was running fine. I then installed the JDK 1.6.0_11 and configured my netbeans to use it.

    I think I'm going to remove JDK 1.6.0 and configure my machine to run 1.5. Is that maybe the reason my the NFC Manager doesn't work? Does it use Java?

    Thanks!

    I uninstalled JDK/JRE 1.6 and reverted to JDK/JRE 1.5.0_16 and the NFC manager is now working fine.

    I hope that this thread will be helpful to someone out there ...

    Re: Can't start NFC manager

    I'm surprised that it didn't work with Java1.6. I wouldn't be surprised if it wouldn't work with 1.5.
    Anyway, you don't need to reinstall/install jre if/when NFC Manager doesn't work with current setup. Copy jre\ folder from jdk installation to C:\Nokia\Devices\S40_Nokia_6212_NFC_SDK\NFCmanager and NFC Manager will use that.
    Directory will look like that:


    d--------- 5 mkpasswd 0 Nov 10 17:40 configuration
    d--------- 4 mkpasswd 0 Dec 4 13:26 jre
    ---------- 1 mkpasswd 57344 Jul 18 07:06 nfcmanager.exe
    d--------- 4 mkpasswd 0 Nov 10 17:41 plugins

    You also can check which version of java was used if you open Help->About NFC Manager->Configuration Details

    Hi!
    I have the same problem with NFC Manager not starting, even after copying the JRE folder.
    I have jre6 and jdk1.6.0_21 installed.
    My OS is WinXP Pro SP3 (32Bit) .

    I would be thanksful for some tips!

    It should work if you follow the instructions in this thread.

    Re: Can't start NFC manager

    I did. Like dubik expected, Installing the JDK5 did not help. Copying the JRE folder afterwards did not help either.

    Maybe I wil try to reinstall my JDK and/or NFC Manager in different orders and maybe it could even help, but I'd like to know what is the problem here.

    Tthanks!
