Interceptors have a method,

handleMessage

, which allows them to act on the Message.These Interceptors can then be built up into chains of interceptors, straightforwardly called InterceptorChains. Some examples include:

...

Bindings provide ways to map concrete formats & protocols on top of transports. A binding contains two main parts, a BindingFactory and a Binding. A BindingFactory builds a Binding from the service model's BindingInfo. The binding contains interceptors specific to the binding and also implements the createMessage() method, which creates a Message implementation specific for that binding. Currently supported protocol bindings include SOAP, REST/HTTP, pure XML and CORBA.

The Soap Binding

...

1. StaxInInterceptor: Creates an XMLStreamReader from an incoming InputStream
2. ReadHeadersInterceptor: Reads the headers into the SoapMessage
3. MustUnderstandInterceptor: Checks the MustUnderstand attributes of all the headers against all the SoapInterceptor's getUnderstoodHeaders method.
4. SoapOutInterceptor:

Pure XML Binding

Transports

CXF includes its own transport abstraction layer to hide transport specific details from the binding and front end layers. Currently supported transports include: HTTP, HTTPs, HTTP-Jetty, HTTP-OSGI, Servlet, local, JMS, In-VM and many others via the Camel transport for CXF such as SMTP/POP3, TCP and Jabber.
