Hi

Yes, we do, it is the CXF JAXRS implementation which is embedded inside the
DOSGI RI but given that the RI is based on CXF it's probably can be
expected. But DOSGi is an open spec.

You should have no problems publishing (RESTful) services on Knopflerfish as
the DOSGI RI DSW component relies on the OSGI ServiceListener. It won't be
possible to run the (REST GreeterService) client on Knopflerfish though
untill it implements the relevant OSGI spec (RFC 119 ?), but it should not
be too difficult to do. In meantime the only option on the client side is to
load the bundles containing code explicitly consuming a remote service
(using proxy-based or http-centric api)...

cheers, Sergey
