Rhino not available in ScriptEngineManager

[Daniel Manresa Menargues]

I need to use rhino for load and run scripts from java.

I have the rhino dependency on my pom, but when i run the application, i obtain a null when i try to load rhino.

My code:

ScriptEngineManager scriptManager = new ScriptEngineManager();

ScriptEngine jsEngine = scriptManager.getEngineByExtension("rhino"); //jsEngine is null after this.

if (jsEngine==null) {

jsEngine = scriptManager.getEngineByExtension("js");

}

If i print all the "EngineFactories" availables i only obtain this:

Anybody knows how to load rhino in Java?

Nashorn replaced Rhino as the JDK provided JSR 223, IIRC, JavaScript interface didn’t it?

Provide your own Rhino interface. My Java shell program, currently known as HalfPipe (a platform for skateboarding tricks),
did this.

Although you can see it is currently broken. This is because I added a global scope function to the interface that allowed it to pid attach to any OS X java process and script it with JavaScript.
This was based on code in tools.jar. I somewhat recently decided to eliminate the tools.jar dependency and broke it.
I roughly plan on getting it working for Java 9 again at some point when that eliminates tools.jar altogether, my understanding.

But anyhow, it would definitely be possibly for you to provide your own interface without that dependency.
