Exporting JOGL project in Eclipse to an executable jar file

Question

I'm currently using Eclipse on Windows as my IDE and I've gotten [JOGL |https://jogl.dev.java.net/] to work on it, however if I try to export the project (I've just got a simple example that runs perfectly through eclipse) to an jar file (either the JAR or Runnable JAR option) the jar file doesn't do anything. If I go to the command line and type "java -jar <the jar file> -Djava.library.path=<where the library files are>" it gives this error:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no jogl in java.library.path
        at java.lang.ClassLoader.loadLibrary(Unknown Source)

        at Snippet209.main(Snippet209.java:75)Clearly I'm missing something. I want to make a jar file that I can send to an arbitrary computer and it will run the JOGL program with no extra steps (or at least as few as possible). Any help would be greatly appreciated with some Duke stars ;-)

Answer 1

Ok, sounds like it would work, although I've never done much with loading libraries like you describe, so I could use some extra notes on it.
I got this code from here and followed the instructions on there too to get JOGL to work with Eclipse:

}I have set up a project in eclipse with that file in the default package. I have created a libs/ folder in the project and I have the following files in it:
gluegen-rt.dll
gluegen-rt.jar
jogl.dll
jogl.jar
jogl_awt.dll
jogl_cg.dll
swt.jarMy project is using the 3 jar files as libraries and I don't need to explicitly say anything about the dll files.
