How do I call a non-public method of a public class in Clojure?

Question

I'm calling the twitter4j library using Clojure like so:

(def twitter (. (TwitterFactory.) getInstance))

This works fine when I call it as a script. But when I use gen-class, I get:

java.lang.IllegalArgumentException: Can't call public method of non-public class: public java.lang.Object twitter4j.TwitterFactoryBase.getInstance()

Is there a workaround for this?

Answer 1

I have no experience with it myself, but Meikel Brandmeyer did a nice writeup on gen-class once, maybe that will help you:

Answer 2

Try:

(def twitter (.getInstance (new TwitterFactory)))
