Hi Javier,
If you set a preverifier.exe property in your sdk.properties file to be ${j2me.preverifier.root}/preverify after your j2me.preverifier.root property is set you can use the preverify.exe that comes with your sdk.
To test, I installed the 3.0.5 sdk in C:\Development\Libraries\Java_ME_platform_SDK_3.0.5 and set the following in my sdk.properties file:
j2me.preverifier.root=C:/Development/Libraries/Java_ME_platform_SDK_3.0.5/bin
preverifier.exe=${j2me.preverifier.root}/preverify
Cheers,
Spencer
