Eugen,
Just FYI, you don't actually have to wait. As Peter aluded, there are
several implementations available now. The spec appears to be
undergoing change but if you want to get started and are willing to
adapt when the spec settles knock yourself out. I have used the ECF
remote messaging to great success in a few cases. You can do the
current distributed services draft spec style or the native ECF style.
Plug in different transports, ...

Thanks Peter,
this is exactly what I wanted to know! I will wait for RFC 119...
Kind regards

The upcoming R4.2 will provide a Remote Services section that allows
you to decouple bundles from the underlying distribution provider.
This means that the only dependency in your code you have on the
distribution provider is a number of properties + the OSGi service
API. These properties should be settable by configuration management.
The intention is that you can switch distribution provider without
changing your app bundles, only have to change the properties. We are
currently working very hard to create the spec based on the RFC 119
for this area and things are still a bit in flux so the RFC 119 is
currently unfortunately a bit stale.
ECF, CXF, and others are implementing this specification as
distribution providers.
Kind regards,
Peter Kriens

Hi,
we are developing a client/server application with osgi. Say I have
three bundles:
1. client
2. common (includes the service interface and domain value objects)
3. server (includes the service implementation)
We've started to develop our application with the remote technology
RMI but switched now to Riena. As it was really a pain to remove all
RMI dependencies from our code (e.g. all RemoteExceptions) I wonder
if there is a best practise approach how to achieve a loose coupling
of a specific remote technology in our osgi bundles without using
tons of wrappers.
Regards,
Eugen
