Re: [concierge-dev] Concierge embedded in JavaFX application

[Tim Verbelen <tim.verbelen@xxxxxxxxxxxxxx>]

Hi,

You will also have to include all used Java FX packages to Constants.FRAMEWORK_SYSTEMPACKAGES_EXTRA if you want to access them from within OSGi bundles. So in this case you should at least add "javafx.scene".

Best regards,

Tim

From looking at your code I could imagine that our use of Constants.FRAMEWORK_SYSTEMPACKAGES is causing the problem. I would recommend to better use Constants.FRAMEWORK_SYSTEMPACKAGES_EXTRA instead because otherwise you are overwriting the defaults and that could cause the resolver to fail because nothing exports org.osgi.framework anymore. The "EXTRA" version keeps the defaults and allows you to add additional packages to it which is what you really want.

Hi Ladislav,

Concierge in JavaFX is an interesting problem and I have not tried that myself, nor am I aware of anybody else who did.
Would you be able to share some basic code/test case that leads to the failure that you describe? That would help us to look into the problem.

I have a problem.
I am embedding (hosting) Concierge in JavaFX application.
I have created bundle. Bundle after install and start change background color in main javafx application, but after start bundle  I get exception.
Is possible embedded-hosted Concierge in JavaFX application? Please any simple example. Thanks._______________________________________________
