Simple Front-end

CXF includes a simple frontend 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 frontend fron-tend will use reflection to intelligently map your classes to a WSDL model.

An interesting feature of the PhaseInterceptorChain is that it is reentrant. This can be powerful and slightly dangerous. This feature is only used in CXF during the sending of an outgoing message, The SoapOutInterceptor is the best example:

public void handleMessage(Message m) {
  writeSoapEnvelopeStart();
  writeSoapBodyStart();

  // invoke next interceptor, which writes the contents of the SOAP Body
  m.getInterceptorChain().doIntercept(m);
  writeSoapBodyEnd();

  writeSoapEnvelopeEnd();
}
