-------------------------------------
Hi Michael,
actually, I did encounter with an issue, but since I was able to avoid it, I
didn't explore it in its full depth. The issue is that
{{AnnotationServiceFactory.createAnnotationService(String)}} does not work in
our environment.
We use probably a bit unusual combination of Equinox 3.8.0 as the OSGi
container with embedded Jetty 8.1.5 as the web container and we use Jetty in
classical WAR-based mode due to historical reasons (our web applications are
not converted into WAB format yet). Despite of this combination, we always
managed to run what we needed after all, but sometimes we meet situations that
might not be expected.
Anyway, back to the issue. At first, I thought it was caused by a wrong TCCL,
which was overridden by CXF. However, the issue in CXF has been fixed (this is
the case of an issue caused by using Equinox), so that the correct TCCL (the
{{WebAppClassLoader}} provided by Jetty) is set. But the issue persists. For
the time being, I overcome it by using
{{AnnotationServiceFactory.createAnnotationService(Collection)}} and providing
the classes directly, which works. I can try to provide more details if you are
interested, it is possible that Equinox (or our weird combination) behaves
somewhat differently from what you expected.
And yet a possibly stupid beginner's question: is there a way to create an
annotation service factory for multiple packages? Because we are at the
beginning of learning OData/Olingo and designing the whole thing, following
idea could be a dead end or another approach could be better, but we were
thinking a bit of the possiblity that available entity types for a service
could come from different bundles which means that the entity classes have to
live in different packages (as we really want to avoid split packages).
