I'm trying to load an FXML document into a Fantom application but I'm getting the error: java.lang.ClassNotFoundException: javafx.scene.layout.AnchorPane

Here is my FXML document (fxmlapp.fxml)

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.paint.*?>

<AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml">
  <children>
    <Label fx:id="label" layoutX="204.0" layoutY="162.0" prefHeight="37.0" prefWidth="225.0" text="Label Here!" />
    <Button fx:id="button" layoutX="204.0" layoutY="218.0" mnemonicParsing="false" onAction="action" prefHeight="24.0" prefWidth="156.0" text="Button" />
  </children>
</AnchorPane>

And my fxml application: (fxmlapp.fan)

using [java] javafx.application::Application
using [java] javafx.scene.layout::AnchorPane
using [java] javafx.stage::Stage
using [java] javafx.scene::Scene
using [java] javafx.scene.control::Label
using [java] javafx.scene.control::Button
using [java] javafx.scene::Parent
using [java] javafx.fxml::FXML
using [java] javafx.fxml::FXMLLoader
using [java] javafx.fxml::Initializable
using [java] java.net::URL
using [java] java.util::ResourceBundle
using [java] java.io::File

class Hello : Application {

    Void main(Str[] args) {
        Application.launch(Hello#->toClass, args)
    }

    override Void start(Stage? stage) {
      URL fxml := File("fxmlapp.fxml").toURI().toURL()
      fxmlLoader := FXMLLoader(fxml)  
      fxmlLoader.setController(Controller.make())
      root := fxmlLoader.load()
      stage.setTitle("FXML-App in Fantom!") 
      stage.setScene(Scene(root))
      stage.show()
    }
}

class Controller : Initializable {
  @FXML protected Void action() {
    echo("TOUCHDOWN!")
  }

  override Void initialize(URL? location, ResourceBundle? resources) {}
}

Lastly I wanted to say: "Wow! What a terrific language this is! Keep up the good work!"

It sounds like just a classpath issue. You can run this command to debug your Java classpath to see what classes the compiler has visibility to:

fan compilerJava::ClassPath

brian - I was thinking the same. I looked around a bit and on http://fantom.org/doc/docTools/Setup.html I saw you can run fan with the java commandline java -cp "%CLASSPATH%;%FAN_HOME%\lib\java\sys.jar" fanx.tools.Fan fxmlapp.fan works great so I'll use that and in my spare time continue to debug the classpath issue through your suggestion. Helpful and responsive community here!
