In this chapter, we covered some very useful extensions offered by the Jersey and RESTEasy frameworks. These features are really useful to address specific use cases that you may see very often in real-life REST API development. Remember that all the features that we discussed in this chapter are not part of the JAX-RS standard (unless otherwise stated). It is always best practice to go with the standard and minimal use of extensions to avoid vendor lock-in. Therefore, if your application really needs some vendor-specific offering, consider all the aspects and then take a decision.

By now, you must have a good understanding of the JAX-RS APIs and reference implementation extensions. In the next chapter, you will learn how to secure RESTful web services.
