JAX-WS Providers allow you to create services which work at the message level - as opposed to the operation level as with annotated classes. The have a single operation "invoke" which receives either the message payload (i.e. the SOAP Body) or the whole message itself (i.e. the SOAP Envelope).
Here's a simple example:
@WebServiceProvider
public class HelloProvider {
public Source invoke(Source request) {
return ....;
}
}Services are publish via one of two means:
-
The JAX-WS standard Endpoint APIs
-
CXF's XML configuration format - i.e. <jaxws:endpoint ... />
