JMF and mp3 plugin

[Wolfgang Tintemann]

I installed the current version of JMF and the mp3 plugin.
When I run the JMFStudio sample app I can play audio
files of .au and .wav format.
When I try a .mp3 file I get the following message :

Unable to handle format: mpeglayer3, 44100.0 Hz, 16-bit, Stereo, LittleEndian, Signed, 16000.0 frame rate, FrameSize=32768 bits

May there be something wrong in my installation or is JMF outdated ?
Is there another Framework which plays audio and video files ?

You 'installed' .. What steps did you take to install these?

And, for an alternative, JavaZoom's MP3SPI.

(I have no experience with either.)
