Hi,
I'm testing JavaFX with Clojure 1.4 and I've got some issues.
I wrote this code:
(ns test-javafx2-clj.core
(:import javafx.application.Application
javafx.stage.Stage
(javafx.scene Parent Scene))
(:gen-class
:extends javafx.application.Application))
(defn -main
"I don't do a whole lot ... yet."
[& args]
(println "Before the launch call")
(javafx.application.Application/launch args))
(defn -start
[this stage]
(println "Arf!"))
;(.setTitle stage "Hello World!"))
My project.clj is the following:
(ns test-javafx2-clj.core
(:import javafx.application.Application
javafx.stage.Stage
(javafx.scene Parent Scene))
(:gen-class
:extends javafx.application.Application))
(defn -main
"I don't do a whole lot ... yet."
[& args]
(println "Before the launch call")
(javafx.application.Application/launch args))
(defn -start
[this stage]
(println "Arf!"))
;(.setTitle stage "Hello World!"))
I build my jar with the command lein uberjar, and when I launch the
generated jar I get this error:
Exception in thread "main" java.lang.RuntimeException: Error: class
test_javafx2_clj.core$_main is not a subclass of
javafx.application.Application
at javafx.application.Application.launch(Application.java:211)
at test_javafx2_clj.core$_main.doInvoke(core.clj:14)
at clojure.lang.RestFn.invoke(RestFn.java:397)
at clojure.lang.AFn.applyToHelper(AFn.java:159)
at clojure.lang.RestFn.applyTo(RestFn.java:132)
at test_javafx2_clj.core.main(Unknown Source)
It's very strange because I well wrote the
:extends javafx.application.Application. So, I don't understand why I've
got this error.
Thanks for your help.
Chris
