With the use of annotations, the JAX-RS API provides a simple development model for RESTful web service programming. In this chapter, we covered the frequently used features of the JAX-RS framework and developed a non-trivial RESTful web service to get a feel of the offerings.

In the next chapter, we will discuss the advanced features of JAX-RS, such as asynchronous REST APIs, advanced topics on filters and interceptors, validations and error handling, custom message body providers, and custom media types. Take a deep breath and be prepared for a deep dive.
