What's wrong with this Jar file?

OpenGL Development JOGL Development
#1

I’m trying to turn my JoGL project into a jar. Can someone tell me what I’m doing wrong?

#2

did you do this on your own or in an IDE?

#3

On my own, why?

#4

cause maybe you made a mistake in specifying the main class. cause an IDE aks you which main class you want.

I am not sure on how to do it without an IDE, but if you can, try it with an IDE

like netbeans, bluej, or eclypse.

#5

Nah, I fixed it. had files in wrong jre.

#6

What files?

Don’t ever put jogl/gluegen jars/dlls in a system or JRE folder!

  • Your jar will only work on your computer
  • You can’t run any webstart app, that uses a different jogl version anymore

Unfortunately solely executable jars are not possible, when using native libraries. Under windows, you can place the dlls in the same folder than the jar as a workaround. This will not work on linux (and mac!?). So you will need a start script for every platform that contains a -Djava.library.path=“path/to/the/folder/containing/the/natives” argument in your java call.

Another option would be to use webstart.

#7

Making your JAR with ANT or in command line with the command jar -cmvf works fine too.

#8

what I maent was, have a program do it for you.

when I meant by yourself, I meant make a zip with the stuff and rename to jarg :stuck_out_tongue:

#9

How do I use JoGL with webstart? That’s what I want to do in the end result.

#10

Best would be to specify the location of the JOGL extension as resource dependency:

Replace the codebase, package , class and jar name with the equivalents from your project and you are done.
