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
    at com.sun.javafx.application.LauncherImpl$1.run(LauncherImpl.java:122)

    ... 1 more

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

EDIT: It works fine in eclipse and in my /Desktop directory. Everywhere else, this exception is thrown.

EDIT2: This is the MANIFEST.MF file built:

Manifest-Version: 1.0
Class-Path: . wfmgr_lib/jfxrt.jar wfmgr_lib/junit.jar wfmgr_lib/org.ha
 mcrest.core_1.3.0.v201303031735.jar wfmgr_lib/gson-2.3.1.jar
Main-Class: main.screens.ScreenFramework

EDIT3: I have both jdk 7 and 8 installed. I set up my eclipse project so its compliance level is java-7, building compatible code for the latter.

I also tried using launcher4J and it only worked (in any directory) with the following configurations:
