Hi,
a) do you require FXCanvas?
b) -Dorg.osgi.framework.bundle.parent=ext has no effect on Java7
because JavaFX is not on a classpath at all
c) if you run on Equinox 3.10 the 1.1.0 hooks can not work as the API
has changed so you need the 2.2.0 adapter hooks
d) if you run with the 2.2.0 adapter hooks you
- should remove org.eclipse.fx.javafx from your target it is not
required anymore
- you have to remove package imports/require bundles to javafx.* and
org.eclipse.fx.javafx as well
e) it is an absolute must that the adapter-hook and osgi.jar at
physically next to each other
f) you can debug the adapter hook with -Defxclipse.osgi.hook.debug=true

Tom,
Thanks so much for your reply, and I apologize in advance for any stupid questions I may ask, as I haven't been working in OSGi very long.
a) No FXCanvas, I'm not using any SWT stuff, just swing, so my integration is through JFXPanels
b) Very good to know, thank you! So there should be no value set for the org.osgi.framework.bundle.parent option, I'll remove those.
c) Where can I get the 2.2.0 adapter hook? The releases are only up to 2.1.0 from what I can see and I'm not sure how to build the main git project to produce a plugin. Where can I get a 2.2.0 target platform?
More to the point, I don't have anything forcing me to keep using 3.10 (I think we went forward to that one because we were originally using JDK8 and that's what Mars was using, which had better JDK8 integration or something), so if I were to go back to Luna or some other version of eclipse, is there a list somewhere of which adapter hook versions are compatible with which versions of org.eclipse.osgi?
d) Does this only apply for 2.2.0+ or would this apply to the 2.1.0 adapter hook?
e) I've definitely been doing this.
f) I have seen that in a few different threads around the web but I have yet to get it to work....what should I be looking for in the output to indicate that switch is working? And is there anything required to get it to work other than just adding it to the command line?
Finally, one question for you. I came across a stackoverflow (not allowed to link to it yet, but the title is "e(fx)clipse 0.9.0 on Kepler with Java 7") where you said what I interpreted to mean that newer versions (i.e. 0.9.0+) required Java8. That's why at one point I started trying to find a combination that would work with 0.9.0...did I misinterpret that? I should be able to get any version of the efxclipse runtime to work with JRE7 right?
Thanks again!
