B4J Question OpenJDK package javafx.application does not exist

[kris A]

I have used Open JDK (https://openjdk.java.net/) not Java SE Development Kit from oracle (https://www.oracle.com/technetwork/java/javase/overview/index.html).

And I found an error while compiling a program as below
with B4J which I got from this forum jsonTree

Compiling generated Java code.    Error
src\b4j\example\main.java:7: error: package javafx.application does not exist
public class main extends javafx.application.Application{
                                            ^
Note: src\b4j\example\main.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

How to use JavaFx Package from OpenJDK in B4J ?
Kindly please help this problem

Haven't tried using OpenJDK to compile. You may need OpenJFX which is not included in openjdk by default.

There is no support for Java 11 at this time.

 

[Erel]

You probably haven't added OpenJFX correctly. Why aren't you using the standard JDK?

@DonManfred , @Erel thank you for your response.

according to https://www.oracle.com/technetwork/java/javase/overview/index.html , "non-commercial" Standard JDK will not be supported again.
i am sure i have added OpenJFX that i've been downloaded from https://gluonhq.com/products/javafx/ , but still not working and i don't know why
any advice?

Thanks

It was discussed in the past. You can safely use the current versions (Java 8, 9 or 10) for many years to come. In the future OpenJDK 11 will be supported. However there is no rush to update.

Ok Erel,

Thank you for your response.
