Hello:
I installed Oracle Java SE 8 JDK for Linux ARMV6/7 on Raspberry PI using Oracle
indications.

Are you sure you are getting the right JRE ? (Are you running with a full path
to java).
The problem is that you are not finding the class javafx/fxml/FXMLLoader which
should be part of the 8.0 and 8u6 JDK.
I probably would have recommended using the instructions at:
https://wiki.openjdk.java.net/display/OpenJFX/OpenJFX+on+the+Raspberry+Pi
because I helped edit those :-)
The JDK mentioned in the tutorial link is pretty old, it refers to an early
access version. The web link above refers to the current released version.
As you may know there are two versions of the JDK for ARM.
The one available for public download should be a full JRE and FXML should just
work.
Java SE Embedded (which allows you to subset the JRE) required 'compact2' to
support FXML. This is the commercial version not available for public download.
compact1 does not have XML support in the JRE and so the FXML classes may fail
to load because they cannot resolve dependencies.
I created an application to run on it and I have an issue loading FXML.
The code is:
private Initializable replaceSceneContent(String fxml) throws Exception {
Locale locale = new Locale("es", "ES");
ResourceBundle rb =
ResourceBundle.getBundle("internacionalizacion.lang",locale) ;
FXMLLoader loader = new FXMLLoader();
InputStream in = Main.class.getResourceAsStream(fxml);
loader.setBuilderFactory(new JavaFXBuilderFactory());
loader.setLocation(Main.class.getResource(fxml));
loader.setResources(rb);
AnchorPane page;
try {
page = (AnchorPane) loader.load(in);
} finally {
in.close();
}
Scene scene = new Scene(page, stage.getWidth(),stage.getHeight()-50);
stage.setScene(scene);
return (Initializable) loader.getController();
}

Do I need install anything else?
Thanks
