Each folder has its own readme!
This is a 4 part piece in which I go through:
- Java Persistence API (JPA)
- Content and Dependency Injection (CDI)
- Rest Services in Java EE
- Combining Rest services, CDI and JPA
- How to create, read, update and delete entities from http requests
- How to persist data outside of wildfly (using datasources)
To fully grasp the concepts talked about in this chapter, it is strongly recommended that you take a look at the first 3 chapters.
