REST has now become a standard way to develop web services and when it comes to Java, there are many frameworks and library available e.g. JAX-RS, Restlet, Jersey, RESTEasy, Apache CFX etc, but I encourage Java developers to use Spring framework to Develop Restful Web services. But, some of you might ask, why use Spring Framework to develop RESTful web services in Java? What is the advantage and why it's better than other frameworks and libraries available out there? Well, the most important reason I think to use Spring for developing RESTful web service is that you can use your Spring MVC experience to develop RESTful web services.
