using a library file from within jar

This is a follow up of this question

What I try to do:
I have an eclipse project that uses th Sigar library in order to get the cpu information (among others). In order to do that Sigar needs a library file to work. Each CPU/OS have a different file, all of which are available.I have to pack this into a jar, that other can use my application as a library.

What I did:
added the available library files to my project and can access them like so

System.setProperty("org.hyperic.sigar.path",System.class.getResource("/lib").getPath());
System.load(System.class.getResource(getClass().getResource(
    "/lib/libsigar-amd64-linux.so").toString()).getPath());

Both of these seems to work if i run my application as a stand alone application. When i pack it to a jar and try to run it from an other project, it just doesn't work. I cant make it to see the directory or the file.
This is the structure of my project
enter image description here
I have tried to access the file with any path i could think of, but all returned a NullPointerException.

How can I do this? Using a temp file? I am not sure how i should do this, i would like to load the whole folder and not just one file, since i dont know the hardware/OS of the client application.
