| Re: [concierge-dev] Concierge embedded in JavaFX application |
Hi,
Indeed, apparently Equinox allows you to set a parent classloader, in this case set to "ext", which means the system classloader will load any of the packages in .jars in the ext folder of the JVM. This will probably contain the javafx packages.
In Concierge we don't have such a property, as this is something Equinox specific (I think) and is not described in the OSGi core spec. The org.osgi.framework.bootdelegation property on the other hand is part of the OSGi core spec, and actually achieves the same result.
Cheers,
Tim

I think that related with line initialProperties.put("osgi.parentClassloader","ext"); What is it?Is it possible for Concierge?Equinox not set none javafx.* packages at starting framework. And also in bundles for sample 'DukePad' below not set none javafx.* packages in header Import-Package in MANFEST:FILE.But I have other question.Thanks all.Problem resolved!
Thanks again to all.

Hi,there are two OSGi properties which are required to understand:
"org.osgi.framework.system.packages.extra" adds Java packages to "Export-Packages" to System bundle (=Concierge)Add here packages if a bundle can not be resolved. If your bundle makes an "Import-Package: javafx.scene" you have to add this to system packages extra as Tim mentioned.In your stacktrace I do not see that bundle can not be resolved, so seems to be OK.
"org.osgi.framework.bootdelegation": adds java packages which will be loaded from System ClassLoader instead of a bundle classloader.Concierge does only load java.* classes from System ClassLoader, which is exactly according to OSGi spec.If you will use other classes from rt.jar (javax.*, sun.*) or in your case (javafx.*) you have to add them to this property.
So: set of org.osgi.framework.bootdelegation=javafx.* may help.
Bye, Jochen

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,

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.

_______________________________________________
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._______________________________________________
