It seems I'm missing a library to run the debugger and JSwat called libjdwp.jnilib and I searched my hard disk and I am indeed missing it. How are other people running JSwat and the Java Debugger?
Here's the specific error message:
Could not find -Xrun library: libjdwp.jnilib (searched /System/Library/Frameworks/JavaVM.framework/Versions/1.4.1/Libraries:.)
