Exposing a function from Java to Rhino

Question

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?

Answer 1

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.
