Ciao,
Stavo provando a realizzare un piccolo lettore mp3 con JMF, ma mi da il seguente errore:

Unable to handle format: mpeglayer3, 44100.0 Hz, 16-bit, Stereo, LittleEndian, Signed, 24000.0 frame rate, FrameSize=32768 bits
Failed to realize: com.sun.media.PlaybackEngine@7b8c1496
Error: Unable to realize com.sun.media.PlaybackEngine@7b8c1496

Sapreste aiutarmi? grazie!

codice:
import java.io.File;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.media.*;
