I have a project in eclipse, runs perfectly fine in the ide when I click run, but I need to export it into a runnable jar file which also works fine. But when I try to run it it throws an exception:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no j3dcore-ogl in java.library.path

I have been googling it for 2 days now, tons of results, none helpful. I export it by going to file->export->java->Runnable jar file->i bubble extract required libraries into generated jar, choose the correct configuration, save the file in a specified folder, then it saves just fine. Or at least so I think. The java.library.path goes to the jre lib folder, but when i run it in eclipse it goes to the .so for j3d, i tried changing it using System.setProperty but to no success. I have a feeling that is the problem, but when I tried to fix it nothing happened. I'm using the most up to date java3d library (1.5.2 I believe).

Any suggestions?

If I set export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/jni it works.
