Java ScriptEngineManager no longer works with Mountain Lion's AppleScript

Question

Ever since I upgraded to Mountain Lion, I can't run my AppleScript code through the Java ScriptEngineManager.

The sample code found on Apple's page (link) returns null for the engine object.

public static void main(String[] args) throws Throwable {
    String script = "say \"Hello from Java\"";

    ScriptEngineManager mgr = new ScriptEngineManager();
    ScriptEngine engine = mgr.getEngineByName("AppleScript");
    engine.eval(script);
}

Anybody know of any workarounds?

Answer 1

I got it working by adding a file named "javax.script.ScriptEngineFactory" in the folder "META-INF/services" of my jar as ytw indicated.

I also have to change a bit of code: language seems to no longer be "AppleScript" but "AppleScriptEngine". So this should work:

    public static void main(String[] args) throws Throwable {
        String script = "say \"Hello from Java\"";

        ScriptEngineManager mgr = new ScriptEngineManager();
        ScriptEngine engine = mgr.getEngineByName("AppleScriptEngine");
        engine.eval(script);
    }

At least this works on my MacOS X Mavericks with JDK 1.7.45...
