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
