Java Web Services
Java provides its own API for creating both SOAP
as well as REST web services.

  Services. It is XML based Java API for building
  web services server and client application.
• JAX-RS Java API for RESTful Web Services
  (JAX-RS) is the Java API to create REST web
  services. It uses annotations for simplifying the
  development and deployment of web services.
