Hi I am implementing a point of sale for my web page. The bank give me some code that I have to install on my server, part of this code are .jar and .so libraries that I have to put on a /lib folder another file is a C library that is /include/EMSec.h

So the bank told me that the libraries must be in a folder that must be on the LIBPATH. The point is that I don´t know where is that, but I was doing some tests and now I have this error

java.lang.UnsatisfiedLinkError: no OasisEMSec in java.library.path
   at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1682)

I think that is important to mention that some part of the code have this statement  "System.loadLibrary("OasisEMSec");"

I don´t know what is the problem, I think I am putting the libraries in a wrong place. Some help with this issue please.
