Actually libgecodej.so is installed in /usr/local/lib/.

In order to set java.library.path, I did the following:

I went to Run-> Run...-> Java Applicaton-> New ->Arguments -> VM 
Arguments.  I pasted  "-Djava.library.path=/usr/local/lib/" to the VM 
Arguments field.

However, I am now getting the following problem:

Gecode native code library failed to load.
java.lang.UnsatisfiedLinkError: /usr/local/lib/libgecodej.so.1.0: 
libgecodeint.so.8: cannot open shared object file: No such file or directory

I don't understand this error...

Cheers,
Luis
