the JSR109 spec says that the J2EE componet we expose  through the JSR
109 should not have any state exist over two invocations. (thay ask to
use stateless session Bean then Container can use any instance of web
service impl EJB to support the service.)

do we abide by this, or we support states as well? If that is the case
our wrapper web service need accsess to the MessageContext (how to give
accsess has adressed bit under security part of the archi doc at wiki)

we may need to set API, but I think we should support remote interface
option as well so JSR109Impl used independent of Container.

sorry I not sure what is client-side interceptor stack is. We discuss
more about this. Looking foward to your comments.
