Executing script inside method with BeanShell

Question

I'm not really sure how I can explain this, but here goes:

I want to be able to "insert" some commands into parts of my code which will be loaded from external files. To parse and execute these commands, I presumably have to use some scripting like BeanShell's eval method. The problem is that it doesn't seem to recognize the instance/method it's inside of. As a very basic example, I want to do something like

    public void somethingHappens()
    {
        Foo foo = new Foo();
        Interpreter i = new Interpreter();
        i.eval("print(foo.getName());");
    }

Is this possible? Should I use other scripting tools?

If you're using 1.6, you can use the built in JavaScript support.

The Java Scripting Programmer's Guide explains how to import Java classes into your script.

Code example 9 in this article explains how to pass objects into the script's scope.
