I'm not familiar with javaFX I just started.
I import the package and I did The VM option but when I try to add a WebView, ImageView or MediaView in the window I get this error causes
Caused by: java.lang.RuntimeException: Exception in Application start method
Caused by: java.lang.IllegalAccessError: superclass access check failed: class javafx.scene.media.NGMediaView (in unnamed module #0x18ebfb54) cannot access class com.sun.javafx.sg.prism.NGNode (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.sg.prism to unnamed module #0x18ebfb54
All the other contents working fine, button, Slider, and so on

Whenever I create a JavaFX project from eclipse, I got compiling error as follows and don't know how to solve the issue:
Eclipse, widows10, Error occurred during initialization of boot layer java.lang.module.FindException: Module javafx.controls not found
What I've done before I got this message: JavaFX 11 is installed, User library(JavaFX) is created and added to a project, Build path is configured, VM argument is added But I still get this error message.
I need to work on a project with JavaFX but this error stopped me from doing my job for several days.
I did exactly what is said in the link.

What seems to be the problem? I really appreciate your help.
I have a Xamarin Forms app in Visual Studio 2019 and I have several static class variables defined in the App.xaml.cs file. I use these variables through out my application. However, when I am on a page of my app and add a property of the Static Class variable to the watch window, I receive the error message:
Watch Window Entry:
App.gvm_WaitingList
Error:
error CS0103: The name 'App' does not exist in the current context.
This makes it very hard to debug when I cannot see the values of properties in these static classes. Here is how the variable is defined in the App.xaml.cs
public static VM_WaitingList gvm_WaitingList;
and then I initialize it in the App constructor as follows:
gvm_WaitingList = new VM_WaitingList();
In searching for a solution I did find talk about the immediate window and adding global:: before the item I want to watch. However, when I do that I get the following error:
Watch Window Entry:
global::App.gvm_WaitingList
Error:
error CS0400: The type or namespace name 'App' could not be found in the global namespace (are you missing an assembly reference?)
Any ideas how to get this to work?
I finally found a way to see these variables. If I prefix the variable in the watch window with the namespace, it will resolve the variable in the watch window. Here is the solution that fixed my problem:
(NOTE my namespace is UniversalCheckInHost)
Watch Window Entry:
UniversalCheckInHost.App.gvm_WaitingList
I hope this helps someone else.
Realm shows errors below when running the app.
Error:(4, 20) error: package android.util does not exist
Error:(165, 89) error: cannot find symbol class JsonReader
Error:(4, 20) error: package android.util does not exist
Error:(165, 89) error: cannot find symbol class JsonReader
When I right click the log and jump to source, it switches to the import android.util.JsonReader line in the proxy class that Realm creates for each RealmObject.
Please help fix. Thanks in advance
I had a similar error and was caused because I was using Realm in a "Java Library" Module.
So if you use different modules in your app, please be sure that the one that uses Realm is an Android module.
JsonReader is only available from API 11, so if you call any of the JsonReader methods from API 9 or 10, it will crash with that exception. Realm should work fine if you don't though.
I am new to JavaFX 2.0 and to do practice I have followed the Oracle example about Line Chart (Stock Monitoring)
http://docs.oracle.com/javafx/2.0/charts/line-chart.htm#CIHGBCFI
Now I would like to ad a CSS class in the same package to modify Stroke, color, etc but I can't succed.
Searching here on StackOverflow I have found
scene.getStylesheets().add(this.getClass().getResource("linechart.css").toExternalForm());
but I still get errors
Exception in Application start method Exception in thread "main" java.lang.RuntimeException: Exception in Application start method at com.sun.javafx.application.LauncherImpl.launchApplication1(Unknown Source)
My java class name is JavaFXApplication2 and CSS class name is linechart.css
Would someone be so kind to explain me where I am wrong?
There is another nice tutorial about the CSS use with Stock Monitoring example here
http://docs.oracle.com/javafx/2.0/charts/css-styles.htm
but I do not know how to add the CSS examples to the java class
Thanks
I suspect that the css file is not being copied to the folder where the java files are compiled. Are you using an IDE? Can you add this line to your app System.out.println(this.getClass().getResource(".").toExternalForm());
and copy the css file to the folder path printed by this line.
You can build the project or copy the css file to the build path.If you using netbeans,you must build the project once after new resource file added.
I am refactoring a hugh action script solution in Flash builder (beta 2) using the flex 4 sdk.
The project does NOT use the mx framework.
What i want to have is:
A big 'MAIN' project
several small 'MODULE' projects. each 'MODULE' class refrences the 'MAIN' project as an External reference (doesnt compile into swf) - this is done by setting link type = external in the 'MODULE' project properties -> library path.
'MAIN' loads a 'MODULE' project on runtime using the 'loader' class.
the problem:
I recieve an error from the MODULE project:
VerifyError: Error #1014: Class [some class in MAIN] could not be found.
PLEASE HELP!
Check which application domain you are loading your module into. The app domain needs to be able to access the class you have externalised or you'll get that error.
It might just be a bug with the beta version of the sdk. It seems like the import of a class in a module created in another project doesn't force it's inclusion in the main swf.
try putting a dummy dependency in you main application class, like:
private var forcedImports:Array = [MyClass];
It fixed some of my problems before.
