Using jogl in runnable jar, manual loading of dll

I'm using the jogl library to make nice 3D plots in my program. To use it in a runnable jar, I use the well-known trick to copy the dll out of it and putting it in a temporary location (for details see this question, also for the loadLib function mentioned below )

The problem is that I keep getting Unsatisfied link errors:

static {
        mylogger().info("Loading jogl DLL");

        // we need to put both DLLs to temp dir
        String path = "MYAPP_" + new Date().getTime();
        try {
            loadLib(path, "gluegen-rt");
            loadLib(path, "jogl");
            loadLib(path, "jogl_cg");
            loadLib(path, "jogl_awt");
            li开发者_高级运维braryLoaded = true;
        } catch(UnsatisfiedLinkError e) {
            mylogger().error("Cannot load JOGL libraries: "+e.getMessage());
        }
}

So, is there something wrong with the order of the libraries included? How can I find out what's the cause of the unsatisfied link error?

If you use the JogAmp "Fat-Jar" layout then JOGL and Gluegen will find and load the native library from inside your runnable jar.

use the following layout inside your jar:

 /natives/<os.and.arch>/libLala1.so
 /natives/<os.and.arch>/libLala2.so
