How to export Java OpenGL (JOGL) from Eclipse?

Question

I recently built a JOGL Application using Eclipse IDE.. It works perfectly fine when i run it on Eclipse..

However I want to make a .jar file for this application so that I can put it on my website..

Unfortunately when I tried to export it, It says:

JAR export finished with warnings. See details for additional information. - Exported with compile warnings: /BUGS/src/main.java - Problem writing /BUGS/.DS_Store to JAR: duplicate entry: /DS_Store - duplicate entry: .DS_Store

I believe this warning wasn't crucial...

but when I actually run the .jar file

It won't run, and says "The Java JAR file "BUGS.jar" could not be launched Check the Console for possible error messages.

I'm sorry I'm a newb.... How do fix this problem? How do I check console for possible error messages?

I found a solution in other forum that suggest me to edit the manifest file, but I don't know where to find a manifest file, because I can only see BUG.jar in my directory after i export the application.. It doesn't come with any manifest file or whatsoever.

Or is there any other way to export JOGL?

Thank you....

Cheers...

It seems that you're trying to re-package an already existent jar, right? – Seldun

No. They are all in .java format... So basically I have multiple .java classes.. and I wanted to make it into 1 single .jar file so that i put it on my web... thanks – Unpeople

Did you "Check the Console for possible error messages."? As far as the manifest goes, it's inside the JAR, which is really just a zip file. – Hellbox

I'm sorry but how do i check the console? – Unpeople

I've got a tutorial for this at http://wadeawalker.wordpress.com/2010/10/24/tutorial-creating-native-binary-executables-for-multi-platform-java-apps-with-opengl-and-eclipse-rcp/. It shows how to export a JOGL app from Eclipse as a set of native binaries that you can redistribute just like any other program (no Java installation is required on the user's machine).

I've seen that problem with .DS_Store before. Try refreshing the project/package. That worked for me.

The best way is to create a "runnable jar" within the Eclipse IDE.All the necessary library files will be packed but there are another set of files called Native files(thos .dll files that u install during JOGL setup) which wont work well even if u add it inside the jar.
