I tried putting all of the files there but still get the same 
java.lang.UnsatisfiedLinkError when trying to invoke the method. When 
issuing the command 
right before the error occurs I can see the correct folders there. Is 
there anything else that would differ between running this through 
tomcat than from prompt?

a native library can only be loaded for one class loader.  This has implications for sharing
the code across applications and for redeploying applications.

I never use System.loadLibrary() in the javacode that does work (outside 
tomcat), do I have to?
