J2ME on Motorola's, builds but emulator crashes

    Hi,
    I've been working on a midlet for the Motorola V300. I build it using
    an Ant file which already properly builds for a Nokia series 60 phone
    using the Nokia SDK. Now I'm trying to do the same for the Motorola
    V300 using their SDK. It passes preverification and builds without
    warning/error, but when I try to emulate it using the Motorloa
    emulator, it crashes after initializing the virutal screen with a
    "class check failed: An unknown error occured while checking the
    MIDlet." Any ideas on what might be causing this?

    thanks,
    kevin

  2. Make sure you're actually running your preverified code and not the
    unpreverified stuff. Also, what JDK are you using?

    Download and incorporate the Antenna project into your ANT environment.
    You can download it from <http://antenna.sourceforge.net>. It'll make
    sure, at compile time, that the JDK is told to spit out the proper
    bytecode format (which seems to be the problem here).
