[gecode-users] Graphical java search under c++.

[Zampelli Stephane]

Hi Guido,

I had to make quite a few changes (pathways, linker options, etc) to get 
GecodeJ 1.0.0 explorer running together with Gecode 1.3.0, even change 
your files.

I will not go into details here, every gecode script crashes with the 
(jni?) exception found in attachement. If you have an idea please tell me.

However, if you have now an explorer working on all platforms, using 
GecodeJ as an explorer may be useless.

Stéphane.
