New Features and Improvements

Jakarta EE 8 is a big release, desired and anticipated by the global community for many years. More than ever before, the whole platform is now even more robust, mature, and stable.

This chapter will cover the main APIs that we can highlight for Jakarta EE 8. Not that they are the only topics covered by this release—far from it—but they have a big role in the enterprise context and are worthy of a careful look inside.

Also, this chapter (as the whole book) will work perfectly with Jakarta EE 9.

In this chapter, we will cover the following recipes:

  • Running your first Jakarta Bean Validation 2.0 code
  • Running your first Jakarta CDI 2.0 code
  • Running your first JAX-RS 2.1 code
  • Running your first JSF 2.3 code
  • Running your first JSON-P 1.1 code
  • Running your first JSON-B 1.0
  • Running your first Jakarta Servlet 4.0 code
  • Running your first Jakarta Security 1.0
  • Running your first MVC 1.0 code
