Hi, you have to pass an instance of INotificationHandler, not the class itself.
(.registerNotificationHandler myClient "123" (MyClass.)) or with proxy (let [handler (proxy [INotificationHandler] [] (handle [notification] here))] (.registerNotificationHandler myClient "123" handler)) Kind regards Meikel -- You received this message because you are subscribed to the Google Groups "Clojure" group.
