js file
=======
1. defineClass("MyTask");
2. var task = new MyTask();
3. task.doSomething();
4. out.println('Hello, World!');

MyTask class
============
public class MyTask extends ScriptableObject {
    ...
    public void jsFunction_doSomething() throws JavaScriptException {
        //doSomething
    }
}

My launcher class
=================
1. Context jsContext = Context.enter();
2. Scriptable scope = new Global(jsContext);
3. Scriptable scope1 = Context.toObject(
       System.out, scope);
4. scope.put("out", scope, scope1);
5. jsContext.evaluateReader(
       scope, scriptFile, _scriptFilename, 1, null);


This works fine for me, however MyTask is an object I want my script
creators to have access to without defining the class first. How can I
expose this object so it is always available to them?


I have tried the following without success. I get the "TypeError:
undefined is not a function." error.

4a. Scriptable scope2 = Context.toObject(
        new MyTask(), scope);
4b. scope.put("task", scope, scope2);

I fail to see what makes MyTask any different than System.out besides
the fact that MyTask is instanced and System.out is a static variable?
