Hi,
Based on what I've seen in the mailing list, I've got the following simple Javafx application:
(module-name <org.kawa.javafx>)
(module-extends <javafx.application.Application>)
(module-export start create-button)
(module-compile-options main: #t)
;;
;;; Application
;;
(define (start (primary-stage :: <javafx.stage.Stage>)) :: <void>
(invoke primary-stage 'setTitle "Hello World!")
(let ((root-pane (<javafx.scene.layout.StackPane>))
(button (create-button
text: "Say 'Hello World'"
event-handler: (lambda (event) (format #t "Hello World!")))))
(invoke (invoke root-pane 'getChildren) 'add button)
(invoke primary-stage 'setScene (<javafx.scene.Scene> root-pane 300 250))
(invoke primary-stage 'show)))
;;
;;; Utilities
;;
(define (create-button #!key (text #f) (event-handler #f)) :: <javafx.scene.control.Button>
(let ((button :: <javafx.scene.control.Button> (<javafx.scene.control.Button>)))
(when text
(invoke button 'setText text))
(when event-handler
(invoke button 'setOnAction (object (<javafx.event.EventHandler>)
((handle (event :: <javafx.event.ActionEvent>))
(event-handler event)))))
button))
;;
;;; Main
;;
(define (main)
(invoke-static <org.kawa.javafx> 'launch))
(main)
When compiling I get the following:
E:\Work\kawa>kawa --main -C hello-world.scm
Jun 07, 2017 4:16:42 PM org.jline.utils.Log logr
WARNING: Unable to create a system terminal, creating a dumb terminal (enable debug logging for more information)
(compiling hello-world.scm to org.kawa.javafx)
And when I run it I get the following:
E:\Work\kawa>java org.kawa.javafx

Exception running application org.kawa.javafx
I would be really grateful if someone could point out what I am doing wrong.
Thanks.

just for test, if you try this:
(define (main)
(let ((tst (invoke-static <org.kawa.javafx> 'launch)))
'())
)
does it change something?
i think the probleme comes that you try to return a static object at the level (toplevel or REPL) of a java function,
if the main function is dynamically generated it can not return a static field, for incomatibility reason, i had such incompatibility problem in a pure java program.

Hi Damien,
I tried the change.
During compilation I received the following messages:
E:\Work\kawa>kawa --main -C hello-world.scm
Jun 08, 2017 6:46:08 AM org.jline.utils.Log logr
WARNING: Unable to create a system terminal, creating a dumb terminal (enable debug logging for more information)
(compiling hello-world.scm to org.kawa.javafx)
hello-world.scm:41:12: warning - void-valued expression where value is needed
When I attempted to run it, the same error messages as before appeared.
Tony

Hm. It works for me. Though I suggest changing the event handler to:
event-handler: (lambda (event) (format #t "Hello World!~%~!")))))
What OS and version of Kawa are you using?
I'm using Kawa 2.93-23-g4fa24f2-dirty (using kawa --version), on Fedora 25.
