Thank you kindly @aeric - I had noticed that it could run that way, however I had incorrectly assumed that a packager was also necessary. Thank you for putting me in the right direction .
Note that for the jar to work with a double click, Java 8 needs to be installed on the user computer. This is not the same as a standalone package which includes the Java runtime.
If this is an issue then you can find in the forum the old B4JPackager (not 11) that worked with Java 8.
