Problem with Java-Packages in JavaFX-Scripts

Hello!
What I'm trying to do is using a class I've built in my project in a JavaFX-Script, my problem is that the compiler keeps telling me my package wouldn't exist.
My filestructure is basically the following:
src
|-com.foo.java
|-- MyClass.java
|-com.foo.javafx
|-- MyFXScript.fx
I've tried importing the package or just writing the fully qualified classname when trying to create an instance, the messages didn't differ. I'm not at home right now so I don't remember the exact compiler-message, but it was something like "Package does not exist: com.foo.java".
Any ideas? :-)
Kind regards,
Joshua

It works on my system.
MyClass.java
package com.foo.java;
public class MyClass {
    @Override
    public String toString() {
        return "My Class";
MyFXScript.fx
package com.foo.javafx;
import com.foo.java.*;
var myClass = new MyClass();
println(myClass);standard-run:
My Class

Javax.* packages not available under JavaFX

Where are the javax.* packages in JavaFX. I want to use some existing libraries that use javax.crypto.* but these packages are not in the rt15.jar??

Just to add some more background.... many of the more popular public APIs use security based on HMAC signatures (e.g. Amazon, Google GData). Typically you use javax.crypto.Mac, javax.crytpo.SecretKey and javax.crypto.spec.SecretKeySpec to implement HMAC.

JavaFX Native Packaging

The JavaFX team has implemented a major new feature for JavaFX 2.2.
Native Packaging uses JavaFX packaging tools to create native bundles for executables, installers and zip files of JavaFX applications (including Java + JavaFX runtimes).
Igor has written a blog on how to use the new feature:
https://blogs.oracle.com/talkingjavadeployment/entry/native_packaging_for_javafx
Give the new feature a spin and log any issues: http://javafx-jira.kenai.com
Not sure of the best way to communicate feedback and suggestions, but you can do that via either this thread or the openjfx mailing list:
http://mail.openjdk.java.net/mailman/listinfo/openjfx-dev

There is information on embedding JavaFX in NetBeans as a NetBeans module in this blog post:
https://blogs.oracle.com/geertjan/entry/javafx_browser_as_a_ready
The official name for Native Packaging is now Self Contained Application.
I do not know how to set a NetBeans application up as a self contained application as I have little experience with NetBeans.
My guess, from your post, is that NetBeans has it's own packaging system for constructing distribution bundles of applications built on the NetBeans platform. Perhaps in this case, rather than packaging primarily with the javafx tools, the packaging should performed by a version of the existing NetBeans packaging system which has been enhanced to support JavaFX modules built on the NetBeans platform. This seems to be the approach you are taking already, but I cannot provide pointers on what changes you would need to make to the NetBeans packager.
Perhaps posts on NetBeans developer forums may yield better answers.

[Urgent] using javafx object in java project

Suppose I here created a very simple java project and the main file is like below,
public class test {
    public static void main(String[] args){
            System.out.println("Hello World!");
}and in this particular java project, I need to use another javafx object which is defined as (the javafx and java file are in the same package),
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.shape.Rectangle;
import javafx.scene.paint.Color;
import javafx.scene.shape.Circle;
var stage: Stage = Stage {
    title: "Declaring Is Easy!"
    scene: Scene {
        width: 300
        height: 250
        content: [
            Circle {
                centerX: 150 centerY: 120 radius: 80
                fill: Color.MAROON
                stroke: Color.INDIANRED
                strokeWidth: 10.0
            }, //Circle
            Rectangle {
                x: 25, y: 80 width: 250, height: 80
                arcWidth: 20 arcHeight: 20
                fill: Color.web("#6699ff")
                stroke: Color.web("#003399")
          strokeWidth: 5.0
            } //Rectangle
        ] //Content
    } //Scene
} //StageSo how could I achieve this?
Regards.

Thanks for your reply.
But would you please elaborate on this sentence: create the fx class using Class.forName("....").newInstance()?
Indeed I implemented an interface which was extended by the javafx class, and in the main java file I need to write following codes to use this object,
Context context = FXLocal.getContext();
        FXClassType instance = context.findClass("packageName.JavaFXClass");
        ObjectValue obj = (ObjectValue)instance.newInstance();
        JavaInterface ji = (JavaInterface)obj.asObject();The problem that I encountered right now is, the exception was thrown at context.findClass("javatest.MyChart");, since it's not able for the compiler to find the JavaFXClass.class.
I checked the folder build\classes\packageName and noticed that both my main JavaClass and JavaInterface have been compiled with .class file, while the JavaFXClass was not, which means the file JavaFXClass.class doesn't exist.
What's the solution?

How to submit a JavaFX app to MAC App Store?

I have packaged my JavaFX application as a self-contained application using simple JavaFX Deployment steps on MAC. According to link "Packaging a Java App for Distribution on MAC ", only the last step is remaining which describes "submitting an app to mac store" . But unfortunately links that lead us to help page are redirecting to the same page and that information is not clearly define steps required to submit a JavaFX app to mac store. Why I need XCode to submit my Java Application to App store? Do I need go through signing steps again, as my app is already sign with valid certificate issued by COMODO? Can I get any help link which guide me to submit my JavaFX app to MAC app store?
Steps so far I have done-
Create a JAR File
Bundle the JAR File into an App Package
Bundle the JRE with the App Package
Sign the App
Now what next to submit a JavaFX app to MAC App Store?

Oracle are working on producing a sample for Mac App Store deployment.
RT-24728 Update Ensemble project to demo how to produce bundle for Mac App Store
The sample is scheduled for the next JavaFX feature release (2.2.60).
You can try contacting the engineer working on the sample to request details.

JavaFX apps for Mac App Store

There is an AppBundler project: http://java.net/projects/appbundler
There are the JavaFX deployment tools: http://docs.oracle.com/javafx/2/deployment/jfxpub-deployment.htm
Oracle documentation for packaging apps for the mac says to use AppBundler:
http://docs.oracle.com/javase/7/docs/technotes/guides/jweb/packagingAppsForMac.html
If I want to package a JavaFX application for delivery to the Mac App Store, should I use the AppBundler or the JavaFX packaging tools?
If the JavaFX packaging tools can be used to package an application for distribution to the Mac App Store, what are the steps to do this?
Can the JavaFX packaging tools also be used for packaging a non-JavaFX Java application for delivery to the Mac App Store?

If I want to package a JavaFX application for delivery to the Mac App Store, should I use the AppBundler or the JavaFX packaging tools?JavaFX tools is way to go. At least long term (as you need to use current beta from http://jdk7.java.net/download.html and it might have bugs).
If the JavaFX packaging tools can be used to package an application for distribution to the Mac App Store, what are the steps to do this? See materials from Scott's talk at JavaOne:
https://oracleus.activeevents.com/connect/sessionDetail.ww?SESSION_ID=8224
We will publish blog on this but it may take some time.
Can the JavaFX packaging tools also be used for packaging a non-JavaFX Java application for delivery to the Mac App Store?yes, see

TabbedPane and SplitPane in javafx 1.2

Hi there,
I have some problems finding the TabbedPane and SplitPane package in javafx 1.2.
I´m new to javafx and doing some Tutorials. Now i got a Project which requires Tabs and some sort of Window splitting.
For example, the tutorial: MyTabbedPane
in Netbeans 6.5.1 with javafx 1.2 installed, theres always the error message "Could not find Symbol" at the "TabbedPane" expression.
I hope you can help, i´m quite frustrated at the moment.
Thanks in advance for any help.

I have some problems finding the TabbedPane and SplitPane package in javafx 1.2.No wonder, they don't exist (yet!).
The article you link to isn't a tutorial but a demo.
At the bottom of the article, there a link to the source of this implementation: mytabbedpane

Linux and JavaFX - blurry

So IBM has switched my work laptop to Linux, which has inspired me to try to package my JavaFX app in Linux (right now I have a PC and MAC version).
But everything looks blurry! I know Linux apparently has FONT issue, but is there anything I can do so my app doesn't look like crap running on Linux?

I wanted to know if i tried linux would it work.
iTunes is not compatible with linux.

Fx:application doesn't support the nested "resources" element

I am trying to use the ant tasks to package up javafx as per this document https://blogs.oracle.com/talkingjavadeployment/entry/native_packaging_for_javafx

Howto make a KeyCombination with a Shortcut Modifier?

Maybe I'm missing something really obvious but I can't seem to define a keycombination using the platform-independent shortcut modifier. According to http://docs.oracle.com/javafx/2.0/api/javafx/scene/input/KeyCombination.html the following should work:
menuItem.setAccelerator(KeyCombination.keyCombination("Shortcut+C"));...but it doesn't. This actually puts 'Shortcut + C' in the menu item (hardly ideal) and it doesn't work on Win7. I also tried:
menuItem.setAccelerator(new KeyCodeCombination(KeyCode.C, KeyCombination.SHORTCUT_ANY));...same problem.
How can I specify a platform-independent keycode combination, ideally as a string so it that it can be shunted off to a preferences file?
Thanks

I'm not sure what you mean. I can press Alt+F and the file menu opens fine. Tested on Windows 7 with JavaFX 2.1b18.

Trying to achieve grow/shrink to nothing effect

I'n trying to create a vertical panel where items can be added which are displayed top to bottom. Each "item" is a box with some interesting information to display and should be shown for a few seconds.
The space where it will be displayed will first grow to make room, then fade in, display for a few seconds, fade out, and shrink back to nothing. When it grow/shrinks, the intention is that the items above and below will make room/close the gap accordingly.
Now, I've gotten quite far to get this to work with two different solutions, but both have a problem.
Solution 1
Put the "item" in a Group. Then use Timelines to animate its ScaleYProperty to simulate the shrinking to nothing effect.
Problem: As soon as I put things in a group, the content of the "Item" is too small (it uses the preferred size instead of expanding to fill available space). If I use a StackPane it looks exactly how I want, but the ScaleYProperty won't work properly then (because StackPane ignores transformations in its size calculations).
I've tried forcing the preferred size to the correct value. Problem: I don't know the correct value, I don't know how to find out how big the "content" area should be. Doing a getWidth() of the vertical panel and substracting the Insets comes close, but there's always a small difference -- in other words, unsatisfactory.
...stuck
Solution 2
Replace the "item" with Rectangles that I resize to make space for the "item" before actually adding it. The shrinking effect works great... but I cannot get the grow effect to work properly because I donot know how big the "item" will be... there's no way to find out how big something will be once added to the scene graph.
Fiddling with adding the item temporarily to the scene graph, then trying to get its size somehow didn't work or had annoying side effects.
So, basically, I'm stuck with both approaches.
First because Groups donot allow their content to fill available space... (and finding out the correct preferred size seems not possible)...
Second because I cannot find out how big something will be BEFORE adding it to a scene graph...
Any ideas what I can still try?

Okay, a fully working example ripped completely out of its context :)
This needs some keyboard control. Press 1/2 to adjust the "Playback rate" and 9/0 to adjust "Volume". In the center of the screen boxes will appear showing what you just did, and will fade out after a while. Adjusting both settings shortly after each other can result in two bars being displayed (this is intended) and shows the effect I want in greater detail.
The part I'm not happy with is where I hard-code the Preferred Width (search for setPrefWidth) because it is not correct (the width is only an estimate and changes when a slider is displayed... so the next slider added gets a different preferred width).
Possible solutions are some other way of "shrinking" a group without using the ScaleYProperty; somehow getting the correct preferred width; somehow getting Group to respect the "available space" for my StackPane... etc...
It works great in my opinion, just this little snag I want to get rid of.

Single Listener for multiple controls

Assuming I have 3 Slider Controls representing 3 different properties of an Object. How could I use a Single Listener/Handler to track the changes from all 3 sliders.

Simply attach the same ChangeListener to all three sliders, but instead of looking at the new/old value parameters, just query all 3 of the sliders for their current values and use those.
