Dynamic JAX-RS Server available or do-able?

[Rice Yeh <ri...@gmail.com>]

Hi,
  Is there such a function available in CXF JAX-RS? I have an application
based on CXF JAX-RS. The application itself consits of many plguins and
these plugins can come and leave dynamically. Hence, OSGi is the platform on
which the application runs. In the application, each plugin (bundle)
provides some resource classes and hence managing these dyanamic plugins is
important for this application. Since JAXRS Server
(org.apache.cxf.endpoint.Server) is immutable, the application has to
destory the server and recreate a new server when a plugin is changed (added
or removed). Now, I would like to know that such a function already exist in
CXF JAX-RS? If not, is it do-able for such a function for CXF JAXRS?

Are you asking if it is possible to have a single JAXRS Server with dynamic
root resources without having to create new Servers ? Please clarify a bit
more. I'm not sure what sort of generic support can we provide, need more
information.

For example, in DOSGi, users can register new resources but each new
registration creates a new Server.
But what if we want say a all the requests being targeted to
http://localhost:8081/service and then delegate them to new dynamic handlers
which come and go ?

Do these new resources you are referring to are related to each other
somehow. Do the share the same interface ?
Can you register a single JAX-RS server with a single root resource bean
which will have the new dynamic resources being injected in (from the
Activator) ? Or may be this root resource will listen via ServiceTracker for
the new resources ? This root resource will only delegate to newly
registered resources. Will it work for you ?
