Re: OSGI bundles for CXF and offering Webservices as OSGI Services

[Eoghan Glynn <eo...@iona.com>]

Hi Christian, All,

Now that the RFC 119 spec is out in the open[1], we've gone ahead and 
committed the initial reference implementation to CXF.

Its in the sandbox for the moment, as it includes a fork of Apache Felix 
   extended with a prototype of the Service Registry hooks I mentioned 
before.

Once the reference implementation of these hooks is complete in Equinox, 
we'll switch over to this and promote the distributed OSGi RI to a 
top-level module.

Cheers,
Eoghan

Hi Eoghan,

that´s great. I will take a look at it as soon as possible.

Greetings
