This chapter was focused on the new Java EE 6 and how it interacts with the new Oracle WebLogic 12c. Of course, this chapter or even this book is too short to discuss them all, but it will give you a good view about how it's implemented in a typical Java EE application, which of course Oracle WebLogic 12c is.
Some key facts about Java EE 6 to remember are:
Designed for the full or lightweight Web 2.0 profile
Innovation: New APIs, new features, further ease-of-use with managed beans, CDI, JSF 2, EJB 3.1, JPA 2, Servlet 3, JAX-RS, and bean validation
The goal is to deprecate APIs that are outdated
With focus on the Cloud, it offers:
Containers
Injectable services
Scale to large clusters
Security model
In the next chapter, we will see how these applications will land in WebLogic Server.
