The later. For straight JAX-WS, there is no difference on the Server side. The sync method is called synchronously. It's just the way the client side is handled that is different. > Stated another way, can the SOAP client make an async call to any operation > listed in the WSDL, or only those operations for which the service side has > specifically configured support for it?

The two async methods are internally pretty much ignored when processing the the SEI looking for WebMethods. They just must have a non-async version that matches them. Our server stubs that we generate implement the interface which is why the impl has to have them. However, that isn't a JAX-WS requirement. The impl could NOT implement the interface, have the SEI interface defined in the endpointInterface attribute of the @webService annotation, and then only implement the sync methods. I just like having the impl implement the interface so if the wsdl changes for any reason, the compiler would catch it. The down side being you have to have "null" implementations for the async methods as well. That said, I have been thinking a bit about somehow allowing the use of async methods on the server side as well and leveraging the continuations support. It's still kind of noodling in my mind.
