When you create the shared library with your JNI call do you link it with
the shared libraries it requires?
Say you have libmyroutine.so and you are trying to create libmyjni.so:
g++ --shared ... -o libmyjni.so -L/appropriate/path -lmyroutine
Now when you ldd libmyjni.so it should show a dependency on libmyroutine.so
