Answer 1

The problem is most likely with your run configuration.

• Go to your Class that contains the main(String[] args) method you wish to automatically run when the jar is called from the command line
• Right-click->Run As...->Application
• Make sure it runs to your satisfaction
• Now go through the export process as before, selecting the newly created launch configuration.

The last step is key.
