How do I generate a .jar application file with a WebView ?

Hello everyone,
I have a project which uses JavaFX technology and I have a problem on creating the .jar file for this project.
My JavaFX uses a webview which loads a HTML file (on my local storage). It seems that it runs perfectly if I run the project on IntelliJ.
But when I try to create the project with artifact from IntelliJ, my project seems like he doesn't load the Html file and I really don't know why...
Any hints ?

P.S.:
I also created a post on stackoverflow -> http://stackoverflow.com/questions/35414634/generating-artifact-of-a-project-in-intellij-with-webview
