Hi,

I want to develop an Eclipse 4 RCP with only one editor built on javafx.

I tried the http://wiki.eclipse.org/Efxclipse/Tutorials/Tutorial4 to check that I succeed to run javafx on eclipse 4. It works.
I tried to create a pure E4 application without javafx. It works.

I added in the part code the following : 

    private Scene createScene() {
        Group group = new Group();
        Scene scene = new Scene(group);
        Button button = new Button("JFX Button");
        group.getChildren().add(button);
        return scene;
    }

	@PostConstruct
	public void createComposite(Composite parent) {
		parent.setLayout(new FillLayout());

		FXCanvas canvas = new FXCanvas(parent, SWT.NONE);

		Scene scene = createScene();
        canvas.setScene(scene);
	}


and tried to run the product : 

!ENTRY org.eclipse.e4.ui.workbench 4 0 2016-11-26 15:21:13.096
!MESSAGE Unable to create class 'test.parts.SamplePart' from bundle '120'
!STACK 0
org.eclipse.e4.core.di.InjectionException: java.lang.NoClassDefFoundError: javafx/scene/Parent


I tried to include jfxrt in the build path with no success.
I tried multiple Target Platform with no success.

Where am i wrong?

In case it can be useful, here is my MANIFEST file :

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Test
Bundle-SymbolicName: Test;singleton:=true
Bundle-Version: 1.0.0.qualifier

Did you add -Dorg.osgi.framework.bundle.parent=ext to your VM-Aguments?

Adding -Dorg.osgi.framework.bundle.parent=ext to VM arguments did not change anything but after some research following parameter make it work:

-Dosgi.framework.extensions=org.eclipse.fx.osgi

-Dosgi.framework.extensions=org.eclipse.fx.osgi is used in e(fx)clipse 1.x

-Dorg.osgi.framework.bundle.parent=ext is for e(fx)clipse 2.x

So it depends on which version of e(fx)clipse you are using.

No Dirk if you embed yourself into an e4 swt application this is still needed the reason is that we need to load the swtfx.jar dynamically Smile

You contradict yourself because the tutorial you reference talks about the a pure e4 on javafx app but your code shows swt so I'm not sure what you want to create
- e4 on swt and embed some javafx
- a pure modern e4 on javafx

app

"I want to develop an Eclipse 4 RCP with only one editor built on javafx."
--> e4 on swt and embed some javafx

I just said that before embedding javafx into e4 on swt, I tried both :
- a pure modern e4 on javafx (from your tutorial)
- a pure swt e4
to check my environment (java 8 + e(fx)clipse etc.)

I do not fully understand how it works right know but I will with practice.

Thanks for your support.

Ok if you start from scratch why do you mix swt and javafx. What is the reason you want to use swt? If you don't have any legacy code I'd go pure SWT or pure JavaFX but not mix both if not absolutely needed

Ah, good to know Smile

Right the only thing we don't require anymore is to add the javafx.* imports. The adapter-hook now works as a last resort lookup with the default class lookup fails.

I did not go full javafx because I though that I would have to re-implement some views for things which already exists.

For example, when extending wizards etc.

Am I wrong?

So do you have already swt code? If not then don't mix go swt or go javafx. What are the views available you want to reuse? Anyways don't mix toolkits Smile

No I just start my project so I have no swt code.

I though that by switching to javafx renderer, I was going to limit the capabilities of the eclipse framework and would have to implement some ui which are already available.

For example, I saw that eclipse framework provides WizardDialog which can be extending.

So my question is, will it be more work to do a custom wizard from scratch in a swt based e4 application or in javafx?

Right e(fx)clipse does not yet have a wizard dialog but there are other javafx libs could just include - e.g. http://controlsfx.bitbucket.org/org/controlsfx/dialog/Wizard.html
