Use AquaFX or AeroFX Themes in e4/Equinox Application [message #1441987]

Hi

I would like to try if it is possible to use the AeroFX or AquaFX themes in equinox/e4 applications. If I just download the jars and wrap them in bundles I get exceptions like this:

[2014-10-10 14:39:57,089] ERROR controls Failed to load skin 'com.aquafx_project.controls.skin.AquaButtonSkin' for control Button@1d189dc[styleClass=button]'Abbrechen'
java.lang.NullPointerException
at javafx.scene.control.Control.loadClass(Control.java:131)
at javafx.scene.control.Control.loadSkinClass(Control.java:712)
at javafx.scene.control.Control$4.invalidated(Control.java:672)
...

I excpected something like this because of the bundle classloaders. My question is: How do I work around this?

My second try was to place the jar in a fragment hosted by org.eclipse.fx.javafx. This does not work, because I can't see the classes in my main bundle, even if I export them from the fragment.

So I am wondering if it would make sense to add buddy classloading to org.eclipse.fx.javafx.

Before I experiment further I was hoping on some thoughts on the subject, so any input is highly appriciated.

Thanks!
Christoph

Hi,

I don't think that buddy classloading can help you (nor you could do
that because o.e.f.javafx is a fragment) and it simply delegates the
classloading to the extension classloader on Java8.

The problem you see is that the CSS is used to apply Skins and whole
CSS-Subsystem is loaded by the extension-classloader, so the only
solution i guess is that you put it in your ext dir.

I wonder how they plan to target this stuff in a modular Java9 but I
don't have a better idea.

I wanted to follow up on this to see if it works, but I am having problems including the library in the runtime.

1) I put aerofx-0.2,jar in the lib/ext of the jdk and I can see it in the JRE System Library Tree

2) To enable the styling it is required to call AeroFX.style();. I'm doing this on @PostContextCreate. Compliation works basically ... I see an access restriction warning on this line ...

3) I made sure to start my e4 application with the same jdk

I still get this exception:

java.lang.RuntimeException: Exception in Application start method
	at com.sun.javafx.application.LauncherImpl.launchApplication1(LauncherImpl.java:875)
	at com.sun.javafx.application.LauncherImpl.lambda$launchApplication$147(LauncherImpl.java:157)

	at org.eclipse.fx.ui.workbench.base.AbstractE4Application.invokePostContextCreate(AbstractE4Application.java:308)

Do I need to do something else to hook the library to equinox?
Or is the access restriction the problem here?

Smile,
Christoph

Equinox-Classloader does NOT see ExtClassPath-Entries by default.

Try launching equinox with "-Dorg.osgi.framework.bundle.parent=ext" this
configures equinox in a way anyone on this planet expects a classloader
hierarchies should look like.

So did you put the jar in the extension classpath?

Thanks Tom for the reply and I realized that I was putting the library in a wrong path (JRE/lib/ext) so when I moved it to %JAVA_HOME%/jre/lib/ext it worked... Thanks!!!
