    I'm using Netbeans 6.9.1 and I have the same error when I use the Symbian SDK 3. Any solution?

    Re: "Failed to connect to Emulator/Device" error

    its very simple !
    thats right that you can not connect to any device when no device connected to your pc
    just right click on your project == > properties ==> and then select symbian emulator for your sdk s60 3rd
    good luck

    Re: "Failed to connect to Emulator/Device" error

    Hi,
    I hope I can post here cause it's the same problem...

    I have Netbeans 6.9.1, Symbian ^3 SDK 1.0 & Symbian Belle SDK 0.6, Windows XP and I have exactly the same problem. I'm getting the error "Failed to connect to emulator/device" in the part "Connect to agent". I configured everything as it should I think and also tried saeed.jackson's solution, but it didn't work

    I hope you can help me

    Re: "Failed to connect to Emulator/Device" error

    Hello schumi1331,

    can you launch the SDK emulator as stand-alone instead of launching it from within the IDE?

    Re: "Failed to connect to Emulator/Device" error

    seems you are the only person helping here

    tried that also, but doesn't work: The emulator window opens and is loading, after 3 or 4 minutes it closes by itself...

    I tried also deinstalling ActivePerl 5.14 and install 5.6 from epoc32/tools/distrib as found somewhere, also replaced JDK 7 with JDK 6 restarting after every step but nothing works...

    I searched a litte bit in my files and found the mainlog in /logs. There I found the same error as here, but it doesn't display when running the emulator: http://www.developer.nokia.com/Commu...e-session-quot

    also googled with that error but nothing wants to work... I'm using a blank Windows XP SP3, no firewall software, no anti virus and Windows Firewall is also deactivated...

    I only installed: Perl, both SDKs, NetBeans 6.9.1 and 7.1, Microsoft C++ Runtime Redistributate x86 (or something like that, needed for msvcr71.dll), JDK 7 (replaced with JDK 6 now), and that's all... do I need any other special thing to run the emulator?

    Re: "Failed to connect to Emulator/Device" error

    Hello schumi1331,

    it could be possibly due to some background activity. Could you check the processes by pressing Cntrl - Alt - Delete and then opening the Task Manager?

    On the list of processes, check if there are multiple java.exe, javaw.exe or emulator.exe instances running (others than those launched by the system). If yes, end the processes first and then try to launch the SDK emulator.

    Hello nikheel.s.joshi,

    thank you for the information.

    About the OS:

    Windows 7 Home Premium
    Is it a 32-bit or 64-bit version?

    Re: "Failed to connect to Emulator/Device" error

    Sofri bastante com isso, mas acabei encontrando o caminho. Pelo menos no Eclipse, que estou usando no momento.
    É só rodar o projeto sem debug, clicando com o direito no nome do projeto no Package Explorer e selecionando Run as >> Emulated Java ME MIDlet
    Após o MIDLet estar rodando no emulador, NÂO fechar o emulador, fechar apenas a tela SKD Progress.
    Em seguida, rodar novamente selecionando agora DEBUG as >> Emulated Java ME MIDlet.
