In this chapter, we explored the advanced offerings in the JAX-RS framework. In particular, we discussed subresources and subresource locators, validations, exception handling, JAX-RS entity providers, asynchronous RESTful web services and interceptors, and filters for JAX-RS applications. We concluded this chapter by discussing the life cycle of all JAX-RS components that we have learned about so far.

In the next chapter, we will learn about the Jersey and RESTEasy framework extensions in detail.
