In this chapter, we covered some of the very useful extensions offered by the Jersey framework. 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 have discussed in this chapter are offered by Jersey and are not part of the JAX-RS standard (unless otherwise stated). Using the Jersey extension features directly in your code may lock down your application with a specific JAX-RS implementation. However, if the JAX-RS implementation that you choose is robust, proven, and as powerful compared to other similar products in the industry, then you are not really losing much by sticking to a specific vendor. Therefore, if your application really needs some vendor-specific offering, consider all aspects and then take a decision.

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