Java EE 6 web services technologies : JAX-WS and JAX-RS

We would be, in this post, focusing on creating web services with RESTful Web Services (JAX-RS)

Some backgrounds:

In Short, Java API for XML Web Services (JAX-WS) is a technology for building web services and clients that communicate using XML. JAX-WS allows developers to write message-oriented as well as Remote Procedure Call-oriented (RPC-oriented) web services.

In JAX-WS, a web service operation invocation is represented by an XML-based protocol, such as SOAP.

Web services are client and server applications that communicate over the World Wide Web’s (WWW) HyperText Transfer Protocol (HTTP). As per World Wide Web Consortium (W3C), web services provide a standard means of interoperating between software applications running on a variety of platforms and frameworks.

We can say application hosted in backend on server to serve data to clients
