J2ME on Motorola's, builds but emulator crashes

[evilkartman]

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

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

Yes, using the preverified stuff, with JDK 1.4.. Any ideas? Thanks in
advance

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).

Did you try my suggestion?
