All right, I agree hiding it in Java sounds good. The problem is that I cannot provide method public static Scriptable jsConstructor(...), because it would allow instantiation of many server objects. However, when I do not provide that method, how can I make Java class Server available in the JavaScript environment as static, singleton type server.
I guess I could define the class like any other in class ScriptableObject, but without a JavaScript constructor I wouldn't know how to create a singleton instance either. I've tried setting server as some sort of top level property and having it refer to the Java class Server, but that didn't work...
