As I wrote in my previous mail to you:

I forgot to mention that you must recompile, but I hope that wasn't the 
problem. I actually did not bother to fix the makefiles but simply 
recompiled manually (everything under Java directory and GUI directory) 
using standard cmd shell and javac. The Cygwin's make didn't seem to 
work very well anyway.

I am actually using BRITE under Linux and only wanted to know how hard 
it would be to get it to work under Windows (part of a sort of proof of 
concept of protability of the system I am working on). I only generated 
one topology (the one that GUI offers when it is started) and it is 
quite possible that not everything is working. For example, I didn't 
bother to fix command line used to call C++ version, since it cannot 
even be compiled under Cygwin without some fixes.

So, to recapitulate:

1. Probably every Java classpath in BRITE source and scripts is broken 
under Cygwin
2. Probably some other paths and command lines are broken
3. It is probably a good idea to run BRITE under Linux or some other 
*nix, if at all possible

Hope this helps.
