I'm getting the dreaded NoClassDefFound for a javafx.scene.layout.BorderPane in an OSGI application.

I have:

(i) used the EFX Eclipse download

(ii) added -Defxclipse.osgi.hook.debug=true and
-Dosgi.framework.extensions=reference\:file\:org.eclipse.osgi.compatibility.state_1.0.0.v20140403-1907.jar,reference\:file\:org.eclipse.fx.osgi_1.1.0.201411050602.jar

to the vmargs in eclipse.ini

(iii) imported package javafx.scene.layout in the manifest for the plugin which refers to the javafx.scene.layout.BorderPane

(iv) ensured the org.eclipse.fx.osgi fragment is enabled in the Run Configuration

Where should I go from here?

Thanks

Robert

Hi,

Your 2nd line -Dosgi.framework.extensions=... is wrong. You are not
pointing there towards jars but it should be a simple name.

So for the FX-Hooks you'd only pass
-Dosgi.framework.extensions=org.eclipse.fx.osgi

Thanks Tom
I made that change, but the noclassdeffound is still there.

What would the next step be?

Rereading your message. I question myself which eclipse.ini did you
change? The one from your application? Do you use a fixed config.ini?

We have wizards to bootstrap a OSGi+JavaFX application did you try to
use those? Take a look what they are producing.

Tom
Your question gave me the answer. I was amending the eclipse.ini for the Eclipse application itself. I needed to add the VM arg to the Run Configuration which is running the application within Eclipse.

Thanks

Robert
