jar not launching - UnsatisfiedLinkError

I have exported my java project into a jar in my desktop (chose the option that creates a project.jar and a project_lib).

When I run java -jar project.jar on cmd, I get this exception:

    Exception in thread "main" java.lang.RuntimeException: Application launch error

I guess it is probably caused by my project's paths but I don't know how to fix this.
