How to start .jar application (that runs with JavaLauncher.app)?

Questions & Suggestions
1

Hello,

I need to start/activate a java jar application that is seemingly usually started on double click by the JavaLauncher.app...

Usual methods don't work (e.g. choosing the java app from the list of running app triggers a "macro cancelled")

What's the workaround ? (Appart from some ugly open folder and double click on the file...)

Thanks,

Nevermind, the "open a file, folder or application" is working with the use default app.
