Exporting java application to runnable jar file

Hello,
I am following COMSOL tutorial about making GUI app from Programming reference manual. Everything works fine when I am running application from IDE (eclipse), however when I am trying to export it as a runnable jar file and run from the command line (java -jar project.jar) I am getting exception:
Exception in thread "main" java.lang.NullPointerException at com.comsol.model.util.ModelUtil.a(SourceFile:44) at com.comsol.model.util.ModelUtil.initStandalone(SourceFile:396) at BeamModelDemo.init(BeamModelDemo.java:36) at BeamModelDemo.main(BeamModelDemo.java:227)
I've tried all options with exporting libraries (export, pack, copy to folder), but the result is the same. Does anyone can explain me the reason of this error? Or maybe there some source where I can read how to properly deploy comsol-java projects?
Thank you.
