I'm the confused one :) I was conflating the two. Daniel Kulp pointed
this out in the Jira ticket, and I've changed the patch so it now
watches for two properties: org.apache.cxf.dosgi.databinding.jaxb and
org.apache.cxf.dosgi.frontend.jaxws. If the first is true, the jaxb
databinding is used instead of aegis. If the second property is true,
the jaxws frontend is used rather than the simple frontend.

I'm confused. Generally, it's Aegis versus JAX-B and Simple versus
JAX-WS. Are you really replacing Simple with JAX-WS, or are you
replacing both?

I'm finally coming back to looking at this issue. I've added a Jira and a
patch at https://issues.apache.org/jira/browse/CXF-2252
Let me know if there's anything I can do to clean up the patch. Since the
current Aegis databinding remains the default, I'm hoping that this patch
can be merged without causing any problems.
Thanks,

Right. In the SOA world, the WSDL is the service contract. In the Java
world, the interface is the service contract. I therefore see no problem
using JAX-WS annotations on the Java interfaces, since they describe how to
translate between Java and WSDL.

Sorry Josh, I didn't notice your response before replying to Sergey.
So in your case, it wouldn't actually be an issue that the JAX-WS
annotations were present on the OSGi service class?

Hi Eoghan,
Yes, it would most likely require JAX-WS annotations on the service
interfaces rather than the impl classes, but IMHO it doesn't break the
OSGI
service model. Perhaps I should explain my use case.
We are building an open source system that must be able to operate in
both a
co-located (one JVM) and distributed topology. For the co-located
flavor,
we don't want to incur the overhead of web service serialization... we
want
direct access to the java services as they were published to the OSGI
service registry. For the distributed topology, we want to allow
adopting
institutions to swap out individual services for their own
implementations
in other languages. And finally, we want our service clients to be
ignorant
of the current topology. Service developers should enable their
services to
be available remotely (by publishing with the osgi.remote property and
using
JAX-WS annotations), but should not necessarily expect the services to
be
remote.
Providing a JAX-WS configuration option shouldn't impact folks wanting
to
stick with aegis/simple. But it does allow projects that want all of
the
benefits of DOSGI to make their web service contracts usable outside of
the
CXF world.
Thanks,
Josh

Hi Josh,
I'm not entirely sold on the desirability of using JAX-WS with dOSGi.
Wouldn't this require that the original OSGi service class was
annotated with @WebService, @WebMethod etc?
And wouldn't this defeat the whole purpose of dOSGi in a sense? i.e.
if the remotability isn't enabled transparently on a largely unchanged
OSGi application, why not just write a straight JAX-WS server-side
application from the get-go?
Sorry if I'm slightly missing the point here. I just wanted to think
through the implications of using a databinding/frontend that's more
intrusive than Aegis/simple.

I just read David Bosschaert's blog entry [1] addressing questions
about
his
RFC 119 webinar. One of his answers sparked another question, and
rather
than contact him directly, I decided to give the wider CXF community a
crack
at it.
I'd like to have the option to specify which databinding strategy to
use
with DOSGI. Currently, the Aegis databinding is "hard wired". I
recognize
that this makes sense for most use cases, since it relieves the
developer
from any wsdl or xsd responsibilities. But it doesn't make sense for
cross-platform use cases (which, interestingly, David mentions right
after
the question "Why don't you use JaxWS?").
The default wsdls produced by the Aegis databinding are not easily
usable
cross-platform. I wouldn't want to provide a developer with a wsdl
that
specifies arg0, arg1, and arg2 as argument names, for example.
Is there interest in allowing the databinding strategy to be
configurable
in
the DOSGI reference implementation? If so, I'd be happy to work on a
patch.
