This is the second of a three-part series looking at how to build RESTful web services. The series covers all aspects of REST services, from basic HTTP-level interactions, through to matching these operations in your existing code and applications, network security, and adherence to REST standards. As the features and your experience with Web Services and REST increases, the methods and solutions for implementation become your focus of attention. The Java ecosystem provides a range of different tools and implementations that provide the basic structure and format for building RESTful aware applications.
