e(fx)clipse runtime in 3.8 and/or Java 7 [message #1319829]

I understand that you don't support Juno (3.8.x) anymore for the E(fx)clipse tooling. But I'm wondering if it still works when you need JavaFX in a Juno-based RCP application.

I have an RCP that runs in 3.8 (never made the leap to 4.x due to the massive UI changes) and am trying to get access to the JavaFX libraries in one of my plug-ins.

I am guaranteed to be running Java 1.7u55 or better in my distributions.

I have tried downloading the JavaFX target and installing it into my RCP Target. So far no luck (I am unable to load any JavaFX classes).

Am I missing something simple here? Is this supported? Can it be?

My plug-in is including dependencies on:
org.eclipse.fx.javafx
org.eclipse.fx.ui.workbench3

I also specified org.eclipse.fx.osgi to be included in my runtime.

No luck. I get class not found exceptions for all javafx.* classes.

Any help? Please? I am trying to put together a proof of concept demo and need to be able to show that JavaFX inside of my RCP is possible ASAP.

Thanks.

Hi,

To make the JavaFX classes loaded at runtime you need to add the
org.eclipse.fx.osgi fragment to your launch config / product definition
and launch your application with
-Dosgi.framework.extensions=org.eclipse.fx.osgi

Make sure you use the 0.9.0 bundles - 1.0.0 won't work because the
Equinox-AdapterHook API has changed.

To check if the adapter-hooks are running you can add
-Defxclipse.osgi.hook.debug=true to get some prints on System.err
informing you about the activity of the adapter hook.

Thanks for the fast reply!

I also needed to add org.eclipse.fx.javafx to my runtime configuration to make it work.
Looks like I was most of the way there before - just missed the extensions property.

Hi James,

right as a minimum you need
* org.eclipse.fx.osgi (fragment) - makes sure the class-resolving is
hooked
* org.eclipse.fx.javafx - provides the javafx-packages (fake!)

Optionally:
* org.eclipse.fx.ui.workbench3

If you launch from inside your IDE you also need to add the
-Dosgi.framework.extensions=org.eclipse.fx.osgi. If you build your RCP
using tycho and the p2-director then p2 will take care of the
appropriate entries in your config.ini - in case you build that your own
make sure the framework-extension stuff is mentionned there!
