This is a problem with the Java 1.4 update... You need to add the
"coreaudio support.jar" class to the boot class path - we will have a
CAJava out that fixes this, in meantime the java dev list can give you
the nitty gritty details

Hi,
I have been having tremendous problems with the Java API's for Midi. I
have been looking at the Apple Java Sample code but neither FindUnits
nor MIDIGraph will run as expected. MIDIGraph compiles as it should
(in Emacs) but generates the following message when run from the > shell:
Exception in thread "main" java.lang.NoClassDefFoundError:
com/apple/mrj/internal/jdirect/ArrayCopy
at
com.apple.audio.util.CAMemoryObject.copyFromArray(CAMemoryObject.java:2
61)
at com.apple.audio.util.CAFString.allocateNewBuffer(CAFString.java:53)
at com.apple.audio.util.CAFString.<init>(CAFString.java:34)
at MIDIGraph.configureMIDI(MIDIGraph.java:114)
at MIDIGraph.<init>(MIDIGraph.java:85)
at MIDIGraph.main(MIDIGraph.java:73)
I've tried building it in ProjectBuilder but that doesn't work either
(exit code 1, after that PB crashes). I have the latest version of the
Developer Tools (I think, December 2002) and the Audio Tools. Sun's
API's doesn't find external Midi Interfaces but works fine apart from
that. FindUnits also generates a NoClassDefFoundError exception.
I may be doing something really studip here but I can't work this out.
Please help, I'm running out of time! I only need my app to be able to
send some really simple Note On/Off messages. I'm running OSX 10.2.6
and have a USB MidiInterface (Tascam US428) with the latest driver.
Thanks!
