UnsatisfiedLinkError: no j3dcore-ogl in java.library.path
提问by user1630850
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:
我在 Eclipse 中有一个项目，当我单击运行时，它在 ide 中运行得非常好，但我需要将它导出到一个可运行的 jar 文件中，该文件也可以正常工作。但是当我尝试运行它时，它抛出一个异常：

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.pathgoes 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.setPropertybut 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).
我已经用谷歌搜索了 2 天了，很多结果，没有任何帮助。我通过转到导出它file->export->java->Runnable jar file->i bubble extract required libraries into generated jar，选择正确的配置，将文件保存在指定的文件夹中，然后保存就好了。或者至少我是这么认为的。在java.library.path去的jre lib folder，但是当我在Eclipse中运行它，它去了。所以对于J3D，我尝试了用改变System.setProperty，但没有成功。我有一种感觉，那就是问题所在，但是当我尝试修复它时，什么也没有发生。我用的是最新的java3d library (1.5.2 I believe)。
Any suggestions?
有什么建议？

If I set export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/jni it works.
如果我设置 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/jni 它工作。
