I have had partial success on this based on this Stack Overllow post…

I had updated my _40 era jdk build to a nice new 1.7.0_51-b13 which had
unfortunately done me no good.
So I added a
META-INF/services/javax.script.ScriptEngineFactory
to the JDK rt. jar
I had set up a standalone java engine lister that now shows…
java Engines
ScriptEngineFactory Info
Factory class:class apple.applescript.AppleScriptEngineFactory
Script Engine:AppleScriptEngine (1.1)
Engine Alias: AppleScriptEngine
Engine Alias: AppleScript
Engine Alias: OSA
ScriptEngineFactory Info
Factory class:class com.sun.script.javascript.RhinoScriptEngineFactory
Script Engine:Mozilla Rhino (1.7 release 3 PRERELEASE)
Engine Alias: js
Engine Alias: rhino
Engine Alias: JavaScript
Engine Alias: javascript
Engine Alias: ECMAScript
Engine Alias: ecmascript
Unfortunately jrunscript still just shows…
runscript -q
Language ECMAScript 1.8 implemention "Mozilla Rhino" 1.7 release 3 PRERELEASE
maybe needs a reboot or something? I don't know yet but if it works from Java
it's good enough for my purposes.
So, this seems a bug. Why have the code and no way to discover it? Shouldn't
there be a change in the build process for this? Has it already been bug
reported?
Meanwhile, I was still thinking about grabbing the source and setting up
something on github with a dylib/jar pair that developers could add to their
projects
to get this scripting engine without hacking JDK/JRE's. Seem a reasonable idea?
I'm not sure if Robert Palmer and Alan Bateman somehow just missed out on this
problem or had a easier or better solution? If so I'd be interested in hearing
it.
