Custom InvokerFactory is RP for JAX-WS endpoints. How does the actual
invocation is done in JAX-WS case ?
You are saying  Invoker does no do any invocations but it must. It
does use InvokerFactory (RP).

JAX-WS also uses RP model and it's called InvokerFactory

I'm sorry I don't quite understand what are you saying above about IDeployable.
IMHO, trying to create a solution will be futile without understanding
how pieces fit together for
CXF JAX-WS Easybeans solutions...I also think that our solution would
involve providing a custom RP which will do exactly what
InvokerFactory does, possibly overriding JAXRSInvoker somehow - only
if providing RP alone won't be enough...But again, that is not enough
in itself - you have to confirm it's working and thus you'll need to
deploy JAX-RS endpoint with Easybeans and thus you need to understand
how CXF JAX-WS Easybeans works

thanks, Sergey
