Java EE (Java Enterprise Edition) General Discussion

Hello All,

Can some body explain me the differences between a document style and rpc style webservices. Apart from JAX-RPC next version is JAX-WS, which supports document style and rpc, I also studied that document style webservices are meant for Asynchronous style of communication, where client would not block until the response is received.

In either way of writing services using JAX-WS, I currently annotate the service with @Webservice, generage the WSDL and from that WSDL I generate the client side artifacts.

Once the artifacts are received, in both styles of communication, I invoke the method on the port. Now, this does not differ in rpc style and document style. So what is the difference and where is that difference visible.


Similarly, in what way SOAP over HTTP differ from XML over HTTP. After all SOAP is also XML document with SOAP namespace. So what is the differnce here.
