Hi Tito,

Yes, thanks for your help about the cpp file ( ld.so.conf not well configured ).
The reason why we are doing this way with JNI is mainly historical: the program
has been done 5 years ago... we wanted to update the QL version in a smooth way.
Of course, if we cannot solve this problem, we'll use the SWIG java interfaces .

Regards,

Pierre
