I've never used the javafx-packager and have always used the above instead. However, I assumed I was missing out on some optimization related to example 9-5 and example 9-6 of Deploying JavaFX Applications: Preloaders | JavaFX 2 Tutorials and Documentation. I always assumed the supported packaging:
1) Loads only the JARs / resources needed to launch the Preloader.
2) Launches the Preloader.
3) Loads all other application JARs / resources.
4) Launches the application.
Now I'm thinking that's only the case for Web Start deployments. For standalone deployments is it the same as a normal Java application where all of the application JARs are included as part of the classpath?
As said, running the jar file instead of exe file the splash screen is displayed.
I printed some logs into splash screen class: when I run the app from the jar this logs are printed, instead when I run the app from .exe file these logs are not present.
At the end I just copy and paste the code from section 9.3.4 (the long startup task example) and it still won't work. After starting the application I only see some black screen flickering at the upper left screen and then the main app shows up.
What I have done:
Using Netbeans 8.0 under Linux(Fedora20 64bit), JDK 1.8u5 ...
On my machine I see only a little black flickering on the left upper screen and then immediately the app is shown...
The only way I can get this to run is to set the custom preloader property in the Netbeans-project properties. If you use a maven based project in Netbeans you did not got this option ...
I'm trying to set up a splash screen where a native splash screen is shown initially and then replaced with the stage from my preloader. This is fairly simple to do. I use the below code to get everything lined up properly.
private void alignStage(Stage stage) { SplashScreen splashScreen = SplashScreen.getSplashScreen(); if (splashScreen != null) { // Align the stage based on the current splash location Rectangle bounds = splashScreen.getBounds(); stage.setX(bounds.getX()); stage.setY(bounds.getY());
[Code] ....
The problem I'm having is that my Stage isn't actually shown by the time the commented event gets fired. The API for onShown says:
Called just after the Window is shown.
My guess is the window has transitioned to being shown, but there's a slight delay until it gets rendered on screen. If that's a decent assumption, is there a reliable way I can make sure my preloader stage is visible on screen before I hide the native splash?
The best option I can think of so far is to delay hiding the native splash until the preloader gets the BEFORE_START notification. This works (no flicker), but, since both splash screens are actually visible for a while, using a transparent splash doesn't work very well (which actually isn't too big of a deal).
I done a small application with Javafx that start an Embedded Jetty. All works fine in Windows also with native package. Instead in Mac it works only before native packaging. Seems that the problem is how relative path are considered.
The tree of the content is this: myfile.jar webapp (folder) libs (folder)
Look at this code:
String webAppDir = "webapp"; File f = new File(webAppDir); log.debug("Path webapp folder: " + f.getAbsolutePath()); if (!f.exists()) throw new Exception("The folder " + f.getAbsolutePath() + " doesn't exist");
[Code] ....
The problem is that before the packaging in Mac the relative path is that where the main .jar is located an so the code works because the webapp folder is found. Instead after the bundle the path became /Users/MyUser/webapp and of course the folder is not found because it is bundled inside the file.app near the libs folder.
I'm working on an application and I would like to package my resources (icons, about dialog images, splash screen images, release version text, etc.) in the jar file I'm going to distribute for deployment. I would like to access these resources from the JAR file in my deployed code. But I would also like them accessible when I'm running the code in my Eclipse IDE. Is there a way to do this using only one code base?
My Eclipse project structure is src (folder) which contains my source code, bin (folder) which contains my class files and res (folder) which contains my resource files.
I am using the javapackager utility to create my deployment JAR and build a self-contained deployment .exe for deploying to Windows.
Is there a way to have the javapackager build a single JAR file from multiple sources (i.e. my bin and res folders)? What do I have to do in my code so that the same code can be used to load resources when I'm running in Eclipse and the self-contained deployment?
I have a custom library I made to make things easier for myself. I used it in a small program in NetBeans and it works fine. When I try to clean and build, it says it can't find the methods from my Library class. How do I get the library packaged into the jar?

I am running my Java code with SecurityManager enabled. The code must load a DLL and invoke methods written in C using JNI. Is there a documentation available describing the permissions needed for native code?
I have a project of biometric integration by java and i have that javaApi with me for that project i need to add native libraries through NetBeansIDE7.4. I am trying like this
Right click on the ProjectSelect PropertiesClick on RUNIn VM Options TYPE -Djava.library.path="D:/bio-metric/SBXPC_CORE_130330/SBXPCJavaProxy.dll" press Ok but still I am getting Exception java.lang.UnsatisfiedLinkError: no SBXPCJavaProxy in java.library.path
I am developing JavaFX application. I have requirement like that javafx application should be always on top. I could not find an option to make it always on top.
I know that oracle has released a statement saying that JavaFX will eventually replace Swing. What is the advantage of JavaFX? The new format, using "stage" instead of JFrame, seemed weird. Why is this change necessary? What benefit do we reap from JavaFX that Swing does not have?
I am using netbeans scenebuilder and I am a little confused on how I would convert my state capitals java code to a javaFX app.
public class StateCapitals { Scanner in; public static void main(String[] args) { readData(); } public static void readData() { // Location of file to read File file = new File("statecapitals.txt");
I've been on this for a while and for some reason I just can't seem to get this to work. I know my code is solid, but it won't display my image. I've tried swithcing the image to different directories and also using different image sizes and types. I even used Orcale's guide to display your image, but still no go! All I get is a blank canvas? There are no errors. I'm also running NetbeansIDE 8 that supports JavaFX and I made sure the project is a JavaFX Application project.
The homework called for me to display it three times - the first one regular, second resized, and the last one rotated. I even deleted the extra images in hope at least one appears.
I'm working on a project right now in JavaFX, and got stuck. I am drawing a path consisting of CubicCurveTo's and I wonder if there's any way to get the X and Y coordinates from certain parts of that path.
Imagine following a curve (path) with a pencil slowly, and every second you take note the X and Y coordinate. I mean I'm not interested in the control points or start and end points, but the points "in between", preferably at a certain interval.
I've searched for many things online, but have trouble knowing exactly which words to search for. "Paths" often bring up file paths, traversing, coordinates etc. all fail to give me any good results.
I tried to be as specific I could, and I don't think my current code is of any interest in this matter.
(The point of it all is that the path should simulate the path a person walks, and I will store the coordinates in a database for every second).
When i press a button, i want to create a new object in my window(that i have created using scenbuilder, so i have a FXML file and a Controller class). In the window where i have a create button, there are also some textfields where you are supposed to enter name and date.
What i want to do is take the input from the TextField and store is temporally in a String variable, Its this strings i want to take the data from when i create a new object on my View. When i try to do something with the TextFields i get multiple errors that i dont understand at all.
I know my code may be very un-structured the absolute right way, i know, but i dont have time reconstructing and trying to understanding new patterns .The object is the circle and the vertical line.

How can I style my own nodes/controls doing this? Basically it amounts to asking how the selectors like ".column-header-background" are associated with sub-structures of my Java control/node objects. So suppose I have something like
.fancy-node .fred .label { ... }
How does JavaFX associate fancy-node and fred with something in my implementation of a Node/Control?
I am new to JavaFX and OpenCV. The Problem is, that JavaFX can't handle Mat objects. First I load an image as a BufferedImage. Then i have to convert this to Mat. Do my image Processing with OpenCV and again convert the result image to a BufferedImage to display in on my UI. Here are the methods for converting Buff to Mat and Mat to Buff I found on the internet:
public static Mat img2Mat(BufferedImage image) { byte[] data = ((DataBufferByte) image.getRaster().getDataBuffer()).getData(); Mat mat = new Mat(image.getHeight(), image.getWidth(), CvType.CV_8UC3); mat.put(0, 0, data); return mat;
[Code] ....
Next I do some OpenCV stuff:
public static BufferedImage hello(BufferedImage img) { Mat source = img2Mat(img); //Convert Buff to Mat BufferedImage outImg = null; try{ System.loadLibrary( Core.NATIVE_LIBRARY_NAME );
[Code] ....
Finally I call the hello method in my controller:
void menuItemTestFired(ActionEvent event) { try { result = ImageProc.hallo(bImage);//bImage is an image I've loaded before. imageView.setImage(SwingFXUtils.toFXImage(result, null));
[Code] .....
Unfortunately I get a lot of errors. Here are the first one:
Caused by: java.lang.UnsatisfiedLinkError: org.opencv.core.Mat.n_Mat(III)J at org.opencv.core.Mat.n_Mat(Native Method) at org.opencv.core.Mat.<init>(Mat.java:471)
I'm using WebView to display an OpenLayers3 map, e.g. Animation example from openlayers.org. When I lock my screen and unlock it, none of the openlayers layers are re-drawn. Sometimes bringing the window in to focus or a small resize of the component will cause the map to go blank. This doesn't occur in any browser I've tested, so it seems to be a WebView specific issue, although it also seems to be layer specific and possibly cache related. I've only tested on Windows, 1.7.0_51 x64 and 1.8.0_05 x64 ....
