It's easy to make objects available to Rhino from Java using ScriptableObject.putProperty, but is there a way to expose a top-level function? That is, can I make it so scripts in Rhino can call foo() and have that call out to Java code?

Umm... yes, you can. Perhaps I'm not understanding your question correctly (what do you mean by "top-level function"?) but if you've exposed java object to Rhino, you can call its methods.

Sorry if I wasn't clear. While I can expose an object, which allows me to call foo.bar(), I'd ideally like to just call bar(). So, by 'top-level function' I mean a function that's a property of the Rhino Scope that's currently executing, if that makes more sense.

Oh, I see. You can define a FunctionObject: https://www.mozilla.org/rhino/apidocs/org/mozilla/javascript/FunctionObject.html and associate it with global (or your current) scope via putProperty()
