That's it for this chapter. So, what did we have a look at? First up, we had to look at usage scenarios of service and events and we talked about what SSEs are and other related technologies. Next up, we implemented the sending of services events on the server side with JAX-RS. Then, we had a look at implementing SSE clients and receiving those events using JAX-RS client APIs as well as HTML. Finally, we implemented the sending of SSE broadcasts on the server side and we implemented a small HTML chat client.
In the next and final chapter, we will have a look at advanced REST APIs.
