If you use JavaFX inside JavaScript, you should use SDK, not just JRE.
Java 8 goes with 2 utils: jjs for running JavaScript on Nashorn engine and jrunscript for running any script engine
jjs command line util
C:\Program Files\Java\jdk1.8.0\bin>jjs.exe -v
nashorn 1.8.0
C:\Program Files\Java\jdk1.8.0\bin>jjs.exe -h
jjs [] [-- ]
-D (-Dname=value. Set a system property. This option can be repeated.)
-cp, -classpath (-cp path. Specify where to find user class files.)
-doe, -dump-on-error (Dump a stack trace on errors.)
param: [true|false] default: false
-fv, -fullversion (Print full version info of Nashorn.)
param: [true|false] default: false
-fx (Launch script as an fx application.)
param: [true|false] default: false
-h, -help (Print help for command line flags.)
param: [true|false] default: false
-scripting (Enable scripting features.)

-strict (Run scripts in strict mode.)

-t, -timezone (Set timezone for script execution.)
param: default: Asia/Shanghai
-v, -version (Print version info of Nashorn.)
param: [true|false] default: false
jrunscript command line util
C:\Program Files\Java\jdk1.8.0\bin>jrunscript.exe -h
Usage: jrunscript [options] [arguments...]
where [options] include:
-classpath Specify where to find user class files
-cp Specify where to find user class files
-D= Set a system property
-J Pass directly to the runtime system
-l Use specified scripting language
