Error preverifying class

[Diana Garc�a]

Hello

I'm trying this JLayerME to play mp3 files with J2ME, but I can't build the project because I get this message:

Error preverifying class javazoom.jlme.util.Player

VERIFIER ERROR javazoom/jlme/util/Player.startOutput(Ljavax/sound/sampled/AudioFormat V:

Cannot find class javax/sound/sampled/Line$Info


I've tried putting the sound.jar everywhere, including in WTK2.1/apps/myapp/lib and it still can't find it. What can I do?

Regards
