Personal Offer

I'm sending to you jfx_activation_key value by e-mail (alternatively you can get it on the site) for any of your Windows™ machines you've bought Personal License for.

Those machines are identified by BOXID, which you are getting from the warning message similar to this:

20 17:21:26 | pool-2-thread-1 | WARN | *************************************************************************
20 17:21:26 | pool-2-thread-1 | WARN | Ask for 'nj4x_activation_key' for your box: id=1128320414
20 17:21:26 | pool-2-thread-1 | WARN | JFX functionality is limited: API methods will respond in random delay.
20 17:21:26 | pool-2-thread-1 | WARN | *************************************************************************

jfx_activation_key then can be set then directly in your Java Application :

System.setProperty("nj4x_activation_key", "1243435406")
.. or from the JVM argument:
java -Dnj4x_activation_key=1243435406 -jar yourApp.jar
