1. is it true only DII support one way communication mode? stub and dynamic proxy doesn't? How they can call void method?
2. stub is used to convert method to message from request, and convert message to request. so stubs take part of job from JAX-RPC runtime?
dynamic proxy does same same is stub? but DII
3. We can use SAAJ to send/consume
SOAP message, so SAAJ can replace stub, dynamic proxy, DII in some degree?
