Apache CXF is an '''open source services framework'''. CXF helps you build and develop services using frontend programming APIs, like '''JAX-WS and JAX-RS'''. These services can speak a variety of protocols such as SOAP, XML/HTTP, RESTful HTTP, or CORBA and work over a variety of transports such as HTTP, JMS or JBI.

Sample project https://github.com/vborrego/cxf-test
