Calling from JRuby

[A. Sundararajan]

Hi James,

You can use jsr223 API to create nashorn engine from JRuby and evaluate 
JavaScript. You can expose Java objects as global variables to script 
(via javax.script.ScriptContext). It is also possible to implement Java 
interfaces and extend Java classes in JavaScript. Objects of such 
implementations can be passed around to JDK core classes as well as 
JRuby classes.

You can access properties of JavaScript objects via 
jdk.nashorn.api.scripting.ScriptObjectMirror.
You may want to refer to 
https://wiki.openjdk.java.net/display/Nashorn/Nashorn+jsr223+engine+notes
