Hi,
So for the last 6 months i have been working on JavaFx and OSGI (Equinox), but as separated Projects, and i have come to the point where i need to integrate these two techs together, so i have tried the two e(fx)clipse brilliant wizards
1- OSGI Application Project
2- OSGI Bundle Project
as a solution for this dilemma and i have come to this (feel obligated to correct me if wrong  ) :
1- for the first wizard it is generating four projects which MR. Tom Schindl had explained in his blog http://tomsondev.bestsolution.at/2012/12/10/my-recommended-project-structure-for-javafx-e4-projects/, but when i looked at the Run Configuration of the launch i realized that it is running as an Eclipse Application  , (and i need to start my system as an OSGI Framework), and notice this, there is a plug-in dependencies which looks like this  , and the main class is extending an AbstractJFXApplication class and using an jfxStart method (not a standard JavaFX App)!!!!  .
2- for the second wizard the generated project has the same structure as an plug-in development project (I SUPPOSE) adding the plug-in dependencies that looks like this  .
Now i am using (eclipse-SDK-4.4-linux-gtk-x86_64-efx-1.0.0-SNAPSHOT) as a development Platform, when i try to run the second wizard generated project after adding simple stage-scene-anchorpane code to it , it works as a stand alone jar,BUT when i try to fire the whole system with Equinox System Bundle as an OSGI Framework i have errors regarding equinox not finding certain JavaFx Dependencies.
Now i kinda have a hint that Oracle didn't added the ((((JavaFx to the JRE Class-path)))) So Equinox Can't see it in run-time, and that led MR. Tom to develop those two wizards and using an adapter Hook to fool equinox.
and i need to develop Plug-in projects (Bundles) and have JavaFx Code in some of them, so the Questions that arises are:
Do i need to add the same Plug-in dependencies as in the first wizard? and HOW?
Any Thoughts Or Ideas are most and very welcome, any guidness or tutorials are most appreciated.
Thanks a lot.
Regards.
PS: if you are going to guide me to e4 apps, please explain Why and How? because i have a very bad experience with it, and the already done part of my project is written as plug-in development.

I don't see what your heading to? You want to run on OSGi so why is it a
problem to start you need to start on OSGi-Framework?
and notice this, there is a plug-in dependencies which looks like this ,
and the main class is extending an AbstractJFXApplication class and
using an jfxStart method (not a standard JavaFX App)!!!! .
Right. We define an IApplication which can be launched:
a) through a command line param
b) interactively through the Console or Equinox APIs

This wizard simply creates a Bundle which has the necessary
javafx-imports so that you not forget about one. We need to this javafx
imports because without it the whole wireing of our fake
org.eclipse.fx.javafx bundle with its adapter hooks won't work.

First of all: JavaFX2 was on no classpath, JavaFX8 is on the extension
classpath but Equinox by default does NOT consult that path.
The wizards are in no way fooling Equinox! What is fooling equinox is
the org.eclipse.fx.javafx & org.eclipse.fx.osgi bundles:
* org.eclipse.fx.javafx simply does the javafx.* exports so that
bundles who import it wire against it
* org.eclipse.fx.osgi hooks into the construction of the classloader
for org.eclipse.fx.javafx and creates one that delegates to one that
knows javafx

You need at least the above 2 bundles.
Or as alternative *none of them* and *no* package imports for javafx
(this important! I repeat no package imports!) but launch Equinox with
-Dorg.osgi.framework.bundle.parent=ext which forces Equinox to NOT strip
the ext-classloader from the lookup hiearchy.
