Open .jnlp file with OpenWebStart in Fedora 39 "TOOLBOX"

Hello,

I am using Fedora 40.

I have a toolbox with Fedora 39.

In that toolbox I have installed OpenWebStart (https://openwebstart.com/). I verified with “dnf list installed”:

openwebstart.x86_64 1.9.0-2 @@commandline

The purpose is to open a .jnlp file with this OpenWebStart.

My challenges:

  1. How to open/run OpenWebStart inside my toolbox? “ows” or “openwebstart” or “OpenWebStart” do not do anything.
  2. I moved my .jnlp file in my “Home” dir (under /.local and “share”?), so I should be able to open that file within my toolbox (with OpenWebStart once I assign this package to my .jnlp file), right?

Thank you for helping.
