This document discusses the creation of a web service using JAX-WS in Mule. It describes adding an HTTP connector, creating a flow called "web_service_calcolo_cliente", and specifying the host, port, and path to activate the flow. It also mentions adding a CXF component to define a JAX-WS/SOAP web service and creating a Java interface for the web service, which includes a method that receives a customer number, performs a drawing, and returns a SOAP message.
