Joining the new GecodeJ - hype ;-) I had exactly the same problem where 
java complained about
undefined symbol: _Z.....someGecodefunction.......

Somehow I realized that I still had configured my Gecode version I'm 
working at using

--enable-static --disable-shared

I just gave it a shot and recompiled Gecode with the standard configure 
options, that is

--enable-shared    [ turned on by default]

Afterwards I recompiled GecodeJ and checked that all the paths are ok, 
that is
PKG_CONFIG_PATH having the path to the installation directory of the 
gecode.pc for setting up the libs and
LD_LIBRARY_PATH having the path to libgecodejava and the path to the 
Gecode libraries

so the funny thing was using shared libraries instead of static ones the 
GecodeJ interface worked out beautifully
using something like

java examples/Money

as described in the documentation.

As I do not know what your "configure"-options were I was just guessing 
you did the same and I hope that
I could help you out on that one.
Maybe you can post them here, if this does not help you.

Best regards
Patrick
