Hi, The problem is that jaxrs:server declaration is interfering, Using jaxrs:server is a non-DOSGi way, with explicit jaxrs:server declarations one provides all the info needed for JAX-RS endpoints be created. DOSGI endpoint publication process is always initiated directly or indirectly by BundleContext.registerService call. Have a look please at http://cxf.apache.org/distributed-osgi-reference.html#DistributedOSGiReference-ServiceProviderpropertiesForConfiguringRESTfulJAXRSbasedendpointsandconsumers,
there's info there on how to register custom providers, from Activators, as OSGI services on its own, or using declarative properties Hope it helps, Sergey On Mon, Jul 11, 2011 at 7:06 AM, mah <[email protected]> wrote: > I am using Apache Felix 3.2.2 with CXF DOSGi 1.2.
