Hi Tim, hi Paul,
I think they had some trouble with resources in Vaadin in OSGi (Vaadin
makes some specific assumptions oabout the file layout I think) and
therefore implemented their own ResourceTracker
(https://github.com/vaadin/flow/blob/master/flow-osgi/src/main/java/com/vaadin/flow/osgi/support/VaadinResourceTrackerComponent.java).
I'm not sure if this can be done in a better way.
Regarding the packaging bug of felix.jetty: Is there an older version of
the bundle where this bug is not included, because I remember
successfully using felix.jetty for Vaadin once?
Is there a bug repot filed for this bug? Otherwise we should do that.
Kind regards,
Thomas

Betreff: Re: [osgi-dev] Vaadin flow works in bnd workspace, fails in
enRoute project
Hi Paul,
The error you’re seeing is a resolution failure because the
"com.vaadin.flow.osgi version=1.2.3” bundle has a requirement in the
“osgi.service” namespace for the service with interface
“org.osgi.service.http.HttpService”. This basically says that the
Vaadin flow bundle is trying to use the HttpService in some way, and
therefore the exported application needs to include a bundle which
provides the HttpService.
Now in fact the Felix Http Jetty implementation used in OSGi enRoute
*does* provide this service, however it is missing the metadata from
the manifest saying that it provides this service. This is a packaging
bug in the Felix Jetty bundle, and is why the resolve fails.
There is a further question, which is why on earth the Vaadin Flow
bundle is using the HttpService? It would be better and easier for them
to use the Http Whiteboard than to use the old HttpService to provide
content…
Best Regards,
Tim

Hi,
Following the process below I have sucessfully managed to run a vaadin
flow bundle in OSGi.
Create vaadin flow bundle in enroute maven project.
https://github.com/QNENet/enRouteQNEFlow-0.0.1Use flow bundle in bnd
workspace and export as jar, which of course contains all necessary
dependencies.java -jar flow.jar works at localhost:8080
https://s3-ap-southeast-2.amazonaws.com/qnenet/vaadinFlow/flow.jar
create application from enRoute archetypeAdd all dependencies as used
in exported bnd workspace flow.jarenRoute app fails.

Any assistance to solve this last (?) hurdle to having an OSGi work
environment for vaadin flow development would be most appreciated.
Thanks
Paul Fraser
