I'm working on building a tutorial to explain how to get GEF5 MVC working in a pure e4 RCP application. That project is hung up on a java.lang.ClassNotFoundException: javafx.embed.swt.FXCanvas cannot be found exception that I am guessing stems from a problem with getting JavaFX working in an e4 RCP app.

I found the e(fx)clipse Tutorial 3 and was excited to have a good example to work from. Unfortunately, I can't get that tutorial to work in Eclipse Oxygen. The instructions for creating a target don't work. I was able to create the e4 Media Application from the JavaFX/Samples project template folder. It was complaining about a bunch of org.eclipse.fx.* required plugins being missing. I assume that is because I couldn't complete the target setup steps.

I've tried several things to work around the problem and everything is failing. Can someone help or could someone update the Tutorial 3 instructions so they work on Oxygen?

Thanks!

Tutorial 3 is to create a pure "e4 on JavaFX"!

If you want to integrate into "e4 SWT RCP" you:
a) need to set up a pure e4 SWT-Target
b) add from the e(fx)clipse updat site the "RCP e4 Target Platform Feature"
c) you need to launch with launch the RCP application with "-Dosgi.framework.extensions=org.eclipse.fx.osgi to" (similar to Tutorial 2)

Hi Tom,

I have a similar issue with Oxygen. The sample e4 Media throws
"Bundle 'org.eclipse.fx.*' cannot be resolved" error on few org.eclipse.fx.* plugins.
Then I created the e4 Media sample using efxclipse.bestsolution.at Eclipse IDE today and now facing the same issue.

I'm not familiar with Eclipse plugin development and therefore get going with a pre-configured sample is my best choice. Appreciate any guidance.

Thanks!
