[Tinyos-help] java compile errors in tinyos-2.x

[Ryan Aures]

Michael,

That worked!  My java directory now compiles correctly, however I am still
getting this same error for Listen:

$ java net.tinyos.tools.Listen
Exception in thread "main" java.lang.NoClassDefFoundError:
net/tinyos/tools/Listen

I get this error for SerialForwarder as well.  Any ideas?  Thank you for
your help so far.

Ryan
