Architectural Representation

...

CXF includes a simple front-end which builds services from reflection. This is in contrast to the JAX-WS frontend which requires you to annotate your web service classes or create a WSDL first. The simple fronfront-tend end will use reflection to intelligently map your classes to a WSDL model.

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:

...

At any point during processing, an interceptor may throw a Fault, or a derivative of a Fault like the SoapFault. This will cause the chain to stop invoking and unwind it. Unwinding consists of calling handleFault on each interceptor that was invoked in reverse order.

...

MessageObserver myObserver = ...;
destination.setMessageObserver(myObserver);

The most common MessageObserver used in CXF is the ChainInitiationObserver. This takes the incoming message, creates a message Exchange & PhaseInterceptorChain, then starts the chain.
