In this chapter, you learned how to create a microservice based on Jakarta EE specifications (JAX-RS, JPA, CDI, and JTA), using Thorntail. We also discussed the limits of the platform with regard to the client-side components, and how to overcome them. You can find the full code described in this chapter in the GitHub repository at https://github.com/Hands-on-MSA-JakartaEE/ch4.

In the next chapter, we will discuss the management of transactions in distributed environments, such as microservices.
