Java code call C++ compiled shared library through Java Native Interface (JNI) throw java.lang.unsatisfiedlinkerror error. Setting LD_LIBRARY_PATH in bashrc is not enough to solve this error, more configurations are need.
Here is an involved example, update LD_LIBRARY_PATH as follow,
# setting LD_LIBRARY_PATH in .bashrc
export LD_LIBRARY_PATH=/opt/intel/compilers_and_libraries_2019.0.117/linux/compiler/lib/intel64:/opt/intel/compilers_and_libraries_2019.0.117/linux/mkl/lib/intel64:$LD_LIBRARY_PATH
Add a custom .conf file to /etc/ld.so.conf.d, for example, intel-mpi-2019.0.117.conf.
# add library path to conf file
/opt/intel/compilers_and_libraries_2019.0.117/linux/mkl/lib/intel64
/opt/intel/compilers_and_libraries_2019.0.117/linux/compiler/lib/intel64
Update system
sudo ldconfig
