Migrating CXF-DOSGi to be complaint with the new OSGi Remote Service Admin spec

[David Bosschaert <da...@gmail.com>]

Hi all,

As you've seen, the CXF-DOSGi 1.1 release is out [1]. Thanks Eoghan!
1.1 is compliant with the current OSGi 4.2 Remote Services spec [2].

In the mean time, in the OSGi Alliance an additional 'Distributed
OSGi' specification is nearing completion: Remote Service Admin [3].
This spec defines a number of APIs used internally in Distributed OSGi
implementations. The APIs define the interaction between the
Distribution Provider, Discovery System and a component called the
Topology Manager. The benefit of implementing this standard is that
you can mix & match components from various implementations together.
For instance if someone provided a compliant Discovery implementation
based on UDDI, you could just replace the ZooKeeper-based one in CXF
with that UDDI one. It would just be a matter of replacing the
bundles.

CXF-DOSGi is the Reference Implementation of chapter 13, and will also
be the reference implementation of chapter 122.

Marc Schaaf has been working on refactoring the CXF-DOSGi
implementation to also be compliant with Remote Service Admin while
maintaining backward compatibility. Marc and I are planning to
contribute this work to CXF-DOSGi trunk over the coming weeks.

This might destabilize http://svn.apache.org/repos/asf/cxf/dosgi/trunk
for a little while, which is one of the reasons why we waited until
after the 1.1 release.

Hope everyone is ok with this.

Best regards,

David

Marc has submitted the first patch to bug 2427.
I'll be applying the patch shortly.

As this is work in progress, here's a summary of a few things that
aren't finished yet:
Remote Service Admin & Topology Manager   (former DSW):
************************************************************
- Support of the HTTP service is not working at the moment as the
complete configuration type handler is deactivated
- Only the Pojo configuration type handler is supported at the moment
the others will follow soon
- The service decorator is disabled at the moment
- Configuration of the Remote Service Admin and the Topology Manager
via the Configuration Admin is not possible
- Most of the test cases from the former DSW are deactivated as they
need to be adapted to the Remote Service Admin and the Topology
Manager

General:
************************************************************
- Local Discovery is missing
- The Systests are deactivated as they are not yet adapted to the new
implementation

Marc and I will be working on resolving these issues.

Best regards,

David

Go for it!

And welcome to the project, Marc.
